javet's Issues

0.9.7 Test Build Issue

this.runtime.getGlobalObject().set("Class",  Class.class);

const Bukkit = Class.forName("org.bukkit.Bukkit")
const Materials = Class.forName("org.bukkit.Material")

let test = Materials.ACACIA_BUTTON

console.log(test)

On the Js Console.log(test) responds with "com.caoccao.javet.values.reference.V8ValueProxy" which im pretty sure is not supposed to happend but if I do .ToString() it responds with the actual name of the enum. This happens with any other value if you try to console.log it

does the NodeModuleModule.setRequireRootDirectory method support to set a path that in jar file resource folder?

my nodejs scripts are in the resource folder, and the app run as a jar file.

the code just like:
Path nodeModulesRoot = new PathMatchingResourcePatternResolver().getResource("classpath:/node/node_modules").getFile().toPath(); nodeRuntime.getNodeModule(NodeModuleModule.class).setRequireRootDirectory(nodeModulesRoot);

an then we get the error:
java.io.FileNotFoundException: class path resource [node/node_modules] cannot be resolved to absolute file path because it does not reside in the file system: jar:file:/app.jar!/BOOT-INF/classes!/node/node_modules

V8 flag support for --max-old-space-size

We attempted to migrate off of J2V8 and all seemed well. We just use the V8 support on Ubuntu 20.04.2 LTS - not the Node support. The coding was relatively simple to migrate and testing passed QA.

However in our production systems with 32GB of memory we run some big jobs that repeatably hit V8 very hard. As soon as we started running Javet on these jobs that crashed our Wildfly 20 server that runs the Javet code and the rest of our code in a webapp.

I suspect the lack of --max-old-space-size, that we used with J2V8. Namely --max-old-space-size=2048 via V8.setFlags("--max-old-space-size=2048");

Looking at the source of the V8Host class method setFlags() , max-old-space-size is not supported. So we skipped it, but that didn't seem to pan out in our big production jobs.

Dynamic Import Callback Handling

Hey, I'd like some sort of way to handle Dynamic Import Callback Handling in Javet

What do I mean by this
I mean a way to compile imports at runtime. import x from 'y'; should let me handle y dynamically through some sort of combat

API suggestions

// This should possibly be able to use some sort of future for delayed imports
v8Runtime.setImportHandler((currentModule, target) -> {
  // Return compiled module?
});

Quarkus compatibility

Have you investigated Quarkus compatibility? Do you think it's realistic to support native builds using GraalVM? If could do some tests if this topic is of interest.

Add support for building Apple M1 native library

Tracking ticket for adding native Apple M1 build support.

I have this working locally for both Node and V8 runtimes. All tests are passing.

I will open a PR shortly once I'm happy the integration with my other project is working correctly.

NodeJs support

Can Javet be used in java program to Run nodejs modules ? Which version of nodejs is supported?

How long you are planning to maintain this project?

javet : Can call java static method?

Error loading lodash

have exception when i use runtime.executeScript load lodash.js . i want add lodash library in javet runtime

Limit Access

Is it possible to limit JS Built in modules. Like Node VM does?
similar to vm2.

Script for Custom Packaging

Background

Currently Javet ships the jar files with both Node.js mode and V8 mode, and with Linux and Windows libraries bundled. That is not flexible and efficient in some cases and the bundle file size usually is large. Some Javet users want to customize the jar files.

Goal

To create a script that allows Javet users to customize mode and OS based on the official releases. The rough workflow is as following.

1. It takes CLI arguments --mode node|v8 --os macos|linux|windows --release x.x.x --output file_path.
2. It downloads the jar files from maven central.
3. It extracts the libraries from the jar files.
4. It packages the new jar file with the selected libraries.

Contribution

If you have done that repeatedly and are interested in this issue, you are welcome contributing to it. Or, it takes low priority at my side, so it would take a long time for me to look into it.

A fatal error has been detected by the Java Runtime Environment

Hello, please see the following error created on a Ubuntu 20.04.2 LTS test server running Wildfly 20 with JDK 11. The OS has 32GB of memory with 50% assigned to Java.

The Javet code version is the latest artifact from GitHub actions for the project, as of today.

I do not have a simple test case; For now I can offer a concise example of the code and the error generated. The method below matches the link of the logs below from the Java error though it is obviously not a full test case.

The logs of my code show "Javet can't setMaxHeapSize, flags are sealed" . I didn't notice that in my last comment in the other issue. The monitoring we use for the server doesn't indicate low memory and the Linux OOM killer is not a factor though the server is getting hit hard so free memory is reduced. This code is executed many times across three servers via web services that are load balanced.

Thank you for your time and promising project. Please set me straight if this is a matter of a simple coding error. The following code is migrated from J2V8.

                   private V8Runtime runtime;

public String runMyCalculations(Long deptID, ATUserBO requestUserBO, Date historicalDate, ATUserViewStateDTO viewStateDTO, List requestedGroupStatsFieldList, Map criteria, Map inputData, List<Map<String,Object>> overrides, Boolean saveToFAR, Boolean anonymize, Boolean verboseLogging, String uuid, RAPIDiagnostics rapiDiagnostics) throws Exception {
try {
V8Host v8Host = V8Host.getV8Instance();
V8Flags flags = v8Host.getFlags();
if (!flags.isSealed()) {
flags.setMaxHeapSize(2048);
} else {
logger.error(logPrefix + "Javet can't setMaxHeapSize, flags are sealed");
}

                            runtime = v8Host.getV8Instance().createV8Runtime();
                            String calculationOutput = runtime.getExecutor(script).executeString();
                        } finally {
                           if (runtime != null) {
                               logger.debug(logPrefix + "starting release ... ");
                               runtime.close();
                               runtime=null;
                               logger.debug(logPrefix + "done release ... ");
                        }
                    }

Unloading library - V8

Description:
We are using the library in an "extension" application which could possibly be reloaded when the user wants.

But this seems to cause issues since the native library remains loaded on the old classloader.

Is there possibly any concise way provided to properly stop or unload the library?
I have tried to remove all references to the classloader that loads javet and classes loaded by that classloader, but it seems calling gc and runFinalization still doesnt unload the library/classloader.

strange TypeError when using JavetProxyConverter

I think it is a strange behavior. Is it expected?

POC:

public class POC {
    public static void main(String[] args) throws Exception {
        try (V8Runtime runtime = V8Host.getV8Instance().createV8Runtime()) {
            runtime.setConverter(new JavetProxyConverter());
            JavetStandardConsoleInterceptor console = new JavetStandardConsoleInterceptor(runtime);
            V8ValueGlobalObject global = runtime.getGlobalObject();
            console.register(global);
            global.set("javaObject", new Object());
            runtime.getExecutor("console.log(javaObject);").executeVoid();
            global.delete("javaObject");
            console.unregister(global);
            runtime.lowMemoryNotification();
        }
    }
}

Output:

Passing a Function into a Java Class

When you pass a Function into a normal Java Class you don't get the V8ValueFunction you get the Function Entity but that can't be turned into a V8ValueFunction.
This is quite an Annoying Issue because I have to turn all my Java Classes into V8ValueObjects with import statements and make work-arounds for the V8ValueFunction.

Cant use SQLite3 module from javet

main.js

var sqlite3 = require('sqlite3').verbose();
const Database = require('sqlite-async')

Database.open('myDB.db')
    .then(db => {
        console.log("good")
    })
    .catch(err => {
        console.log(err)
    })

java code:

  V8Host v8Host = V8Host.getNodeInstance();
  V8Runtime v8 = v8Host.createV8Runtime();
  v8.getExecutor(new File("main.js")).execute();
        
  Scanner in = new Scanner(System.in);
  System.out.println("running...");
  in.nextLine();

I get an error:

Error: A dynamic link library (DLL) initialization routine failed

The code above works fine on Node.js

Promise is not collected if in a JS function

I have a sample code that executes a JS function that internally collects a promise. PROMISE is never collected when executed in a function. Promise is collected if it is not in a function.

function run()
{
	new Promise((resolve, reject)=>{ resolve("SUCCESS"); }).then(x => console.log(x))
}

Static methods with JavetProxyConverter

Hi! So I was doing some testing with JavetProxyConverter, and encountered the following problem:

If I have an instance of a class, say Class<my.pkg.StaticClass>, I can't access its static methods. There are a lot of libraries in Java which use classes with static methods.

Could JavetProxyConverter proxy static methods of Class instances?

undefined symbol: node_module_register

Hello, I have a problem. My node service contains a package of addon.node files. Here is the error message. How to solve it?

@V8Function( name="get" ) doesn't seem to work properly

Hi,

The following is a failed attempt to a workaround for this issue

Lets assume that some class Registry:

public class Registry {
  @V8Function( name="get" )
  public function Entry fetch( String key ) {
    System.out.println( "call to Register.fetch( '"+key+"')" );
    // magic implementation
  } 

  // ...etc...
}

Then somewhere else in the code we bind the registry to a runtime:

  // Create the registry and bind it to the runtime...
  Register registry = new Registry();
  try (V8ValueObject object = runtime.createV8ValueObject()) {
    result = runtime.getGlobalObject().set( "registry", registry );
    object.bind(registry);
  }

Then when executing the following runtime.getExecutor("registry.get( 'some-key' );").executeString(); results in the following error: TypeError: registry.get is not a function'.

Exposing node flags

Would be nice if we could pass nodejs flags like --inspect from javet when creating the NodeRuntime

JavetProxyConverter: "new" on proxied static classes

Hello! So let's take a class like for example, java.lang.Thread (just as an example)

const Thread = Class.forName('java.lang.Thread');

If I want to initialize an instance of this class via JS, I should be able to do something like new Thread(() => console.log('Hi!')), but you can't because this isn't supported.

The desired output would be a proxied instance of Thread that we can interact with. The example of passing in a JS function as an argument is based on the expected behaviour that these functions will be converted to whatever the functional interface needed is

Thanks!

@V8Function can't handle 'get( id )' methods

Hello again,

Lets assume that some class Registry:

public class Registry {
  @V8Function
  public function Entry get( String key ) {
    System.out.println( "call to Register.get( '"+key+"')" );
    // magic implementation
  } 

  // ...etc...
}

Then somewhere else in the code this happens:

  // Create the registry and bind it to the runtime...
  Register registry = new Registry();
  try (V8ValueObject object = runtime.createV8ValueObject()) {
    result = runtime.getGlobalObject().set( "registry", registry );
    object.bind(registry);
  }

Executing the following runtime.getExecutor("registry.get( 'some-key' );").executeString(); yields the following (unexpected) output:

call to Register.get( 'get' );
call to Register.get( 'some-key' );

I think that the problem is that the method name (Registry.get) somehow conflicts with the internal pattern matching logic of Javet.

add V8Property annotation

你好，很开心试用您的 javet 项目，我的英文很糟糕，但我觉得您应该能看懂中文。
我在学习使用时发现只有 V8Function 。例如：

package kd.bos.olapServer

import com.caoccao.javet.annotations.V8Function
import com.caoccao.javet.interop.V8Runtime

class ScriptDimension(
    private val v8Runtime : V8Runtime,
    private val realObj : DimensionNode
) {
    @get:V8Function
    val name : String get() = realObj.name
}

当我注入这个实例后，我的 js 脚本只能这样使用（accounts就是我注入的ScriptDimension实例）：

accounts.getName()

这些书写对用户不友好，我希望是：

accounts.name

我查看了代码的实现，我发现只有 V8Function 注解，我希望能够增加： V8Property 这样的注解。

package kd.bos.olapServer

import com.caoccao.javet.annotations.V8Function
import com.caoccao.javet.interop.V8Runtime

class ScriptDimension(
    private val v8Runtime : V8Runtime,
    private val realObj : DimensionNode
) {
    @V8Property
    val name : String get() = realObj.name
}

您觉得这个主意如何？

---

Hello, I am very happy to try your javet project. My English is very bad, but I think you should be able to read Chinese.
When I was learning to use it, I found that there was only V8Function. E.g:

package kd.bos.olapServer

import com.caoccao.javet.annotations.V8Function
import com.caoccao.javet.interop.V8Runtime

class ScriptDimension(
    private val v8Runtime: V8Runtime,
    private val realObj: DimensionNode
) {
    @get:V8Function
    val name: String get() = realObj.name
}

When I inject this instance, my js script can only be used like this (accounts is the ScriptDimension instance I injected):

accounts.getName()

These writings are not user-friendly, I hope they are:

accounts.name

I checked the implementation of the code, and I found that there are only V8Function annotations, and I hope to add: V8Property annotations.

package kd.bos.olapServer

import com.caoccao.javet.annotations.V8Function
import com.caoccao.javet.interop.V8Runtime

class ScriptDimension(
    private val v8Runtime: V8Runtime,
    private val realObj: DimensionNode
) {
    @V8Property
    val name: String get() = realObj.name
}

What do you think of this idea?

hwo to register a class

function _test()
{
var _pt = new JavaPoint;
_pt.x = 20;
_pt.y = 30;
var pt2 = new JavaPoint(78,69);
}

what shoud I do to define JavaPoint in Java?
is like @V8Function named @V8Class?

@DaTa
@AllArgsConstructor
@NoArgsConstructor
@V8Class?
public class JavaPoint {
private int x;
private int y;
}

thanks

Javet requires gcc installation on linux, but works fine on windows

Stack-trace from Linux: https://paste.helpch.at/emikeyuhug.md

Question:
The native libraries seem to be loading fine on windows , but it seems to require gcc 6 to be installed for it to work on linux. Is this intended or some bug?

If this is intentional, is there anyway to package the required libraries along with the jar?

Additional Request:
Could you open your DMs on twitter so we could communicate better?

Thank you.

Demo for debugging in Inspector

I want to debug JS code, create breakpoints, watch variables and call stack. First load scripts first and call it from Console manually or throught backend program periodically. When hits the breakpoint, execution should suspend and make it possble for user to debug.

V8Inspector meets my demands, but when I try the CDTShell demo in the tutorial. JS scripts submit in Java didn't show up in Source panel. Could you please create a more complex demo for CDT and remote debug.

How to use FS module?

As I understand it, it can be used if its object is obtained through (v8 Runtime.get Node Module("fs", NodeModuleAny.class )maybe (naturally I use V8Host.getNodeInstance().createv8runtime()), but via require('fs') in the script it doesn't work

Injecting a full Java instance into the V8 Context

So I am trying to expose Java functionality to the V8 context and for this and I would need to be able to inject instances of objects (not necessarily POJOS) into the V8 context. And while this is already possible, the process itself is a bit painful and hard to mantain ( unless I'm doing something wrong). I created a very small basic sample of what I mean.

Let's imagine this is the class of the instance I want to inject:

public class FileUtils {

    private String prefix;

    public FileUtils(String prefix) {
        this.prefix = prefix;
    }

    public void doA() {
        System.out.println(prefix+ "A");
    }

    public void doB() {
        System.out.println(prefix+"B");
    }

    public void add(Integer v1, Integer v2) {
        System.out.println(v1 + v2);
    }

}

Let's imagine this class belongs to an external library and has many many more methods with all sorts of diferent signatures. When I create a new instance of FileUtils, I would like to be able to inject that instance directly into the V8 context along with all those methods inside it, which, when called from javascript would trigger the java code inside them as shown above. So this is how I'm doing this at the moment:

I created a JavetObject converter and created a callback for every method inside the FileUtils class:

@SuppressWarnings("unchecked")
public class EntityConverter extends JavetObjectConverter {

    @Override
    public V8Value toV8Value(V8Runtime v8, Object object) throws JavetException {
        V8Value v8Value = null;
        V8ValueObject v8ValueObject = null;

        v8Value = super.toV8Value(v8, object);
        if (v8Value != null && !(v8Value.isUndefined())) {
            return v8Value;
        }
        Class objectClass = object.getClass();
        v8ValueObject = v8.createV8ValueObject();
        for (Method method : objectClass.getMethods()) {
            String methodName = method.getName();

            try {
                FileUtilsCallbacks call = new FileUtilsCallbacks(v8, (FileUtils) object);
                JavetCallbackContext callback = new JavetCallbackContext(call, call.getMethod(methodName, method.getParameterTypes()));

                v8ValueObject.setFunction(methodName, callback);
            } catch (NoSuchMethodException ex) {
                Logger.getLogger(EntityConverter.class.getName()).log(Level.SEVERE, null, ex);
            }

        }

        v8Value = v8ValueObject;
        return v8.decorateV8Value(v8Value);

    }
}

And I created a JavetCallbackReceiver:

public class FileUtilsCallbacks extends JavetCallbackReceiver implements IJavetCallbackReceiver {

    private FileUtils myInstance;

    public FileUtilsCallbacks(V8Runtime v8Runtime, FileUtils myInstance) {
        super(v8Runtime);
        this.myInstance = myInstance;
    }

    //delegate the calls to the original instance 1 by 1
    public void doA() {
        this.myInstance.doA();
    }

    public void doB() {
        this.myInstance.doB();
    }

    public void add(Integer v1, Integer v2) {
        this.myInstance.add(v1, v2);
    }

}

And finally putting it all together:

 public static void main(String[] args) throws JavetException {
        V8Runtime v8 = V8Host.getNodeInstance().createV8Runtime();

        FileUtils fileUtils = new FileUtils("Hello ");

       //create converter
        EntityConverter converter = new EntityConverter(); 
     

      //convert the fileUtils instance to a V8ValueObject
        V8ValueObject val = (V8ValueObject) converter.toV8Value(v8, fileUtils); 
        v8.getGlobalObject().set("fileUtils", val); //inject it into the V8 context
        
        //call the methods inside the fileUtils instance from javascript
        v8.getExecutor("fileUtils.doA(); fileUtils.doB(); fileUtils.add(1,1);").execute();

    }

All of the above is working perfectly without any issues. So what is the problem? Well, my issue here is with the JavetCallbackReceiver (FileUtilsCallbacks ), I had to duplicate every function inside the FileUtils class to put it inside the JavetCallbackReceiver (FileUtilsCallbacks ). For classes with many many methods, it's painful to have to duplicate each and every method. Is there a better way to achieve this without duplicating code and making sure it applies to all methods inside the classes?

Java Interop without Interception

Description: Javet seems to not be able to directly interact with Java classes without "intercaption" which seems to not be an option since the classes provided do not entirely belong to the project itself.

Question: Could you guide us to any way we could potentially work around this to have it use reflection?

Thank you.

Suggestion: Github actions to make dev Builds

Its a simple as the title, Probs not as simple to make but it might work. Making github actions to build the dev branch each commit would be nice so if we wanted a feature that you have made but not released it. this way we can obtain a jar easily and use it in our projects

Upgrade Node.js to v16 When it is LTS

Node.js v16 will be LTS on Oct 26, 2021. Javet is going to catch up with it. There might be backward compatibility issues with applications that are using Node.js v14.

The plan is to have Javet v1.x.x use Node.js v16, and v0.x.x use Node.js v14. New features, bug fixes, etc. will go to v1.x.x first. v0.x.x will get low priority in terms of cherry-picking changes from v1.x.x, supporting legacy releases.

In order to balance the development and support resource, you are encouraged to leave your choice here. Thank you.

SIGSEGV in JRE on calling Java function

Hi,

I've been experimenting with Javet (great job, BTW!) and I'm facing this strange behavior:

I need to run a blessed application. I registered a dummy function that just returns a string:

try (final var v8Runtime = V8Host.getNodeInstance().createV8Runtime()) {
    final var javetCallbackContexts = v8Runtime.getGlobalObject().setFunctions(callbacks);
    v8Runtime.getExecutor(new File("test.js")).execute();
}

It works perfectly fine when being called from the top level of my script:

console.trace('Here works fine');
myFunction();

Trace: Here works fine
    at /home/void/connector/test.js:84:9

However, if I call myFunction from a blessed's event handler, it fails:

tree.on('select', function(node) {
    console.trace('Here it fails!');
    myFunction();
});

Trace: Here it fails!

Could you please help me?
Is there any more info I can provide?

Can javet be used in Android system?

As J2V8, can javet be used in Android system?
lib, the .so file, can be found.

JavetProxyConverter: Interfaces

Hello! In java, interfaces are represented by java.lang.Class via reflection, and you can check if its an interface via type.isInterface(). I'm suggesting we allow for the conversion of interfaces in Java reflection to V8 via JavetProxyConverter

const interface = Class.forName('my.java.Interface');

There is a few benefits to this.

• Check if another proxied object is an instance of this java interface.
• Creating instances of this interfaces via proxies.

There may be others but I haven't thought of them. Thanks!

Osgi compatibility for Javet

Javet 0.9.13 when used within an OSGi container fails to function throwing the below error:

java.lang.UnsatisfiedLinkError: com.caoccao.javet.interop.V8Native.createV8Runtime(Ljava/lang/String;)J
    at com.caoccao.javet.interop.V8Native.createV8Runtime(Native Method)

This is because the custom OSgi bundles fail to see the javet native library file dll on Windows.

We would need to support Windows/MacOS/Linux OS as well

Can not run script from root

Not working:

Working:

Is possible to make working both?

btw. thx for awesome lib ;-)

how to call V8ValueFunction and get return value

My method has many parameters that need to be passed in, but it does not work.

use @V8Function to reg function with ... args, in js call fn() with no arg error

I register ...args with @V8Function like this:

@V8Function(name = "testparam")
public void testParam(int... param) {
int[] params;
params = param;
log.info("testParam param:{}", params);
}

in js I call like this:
testparam(); //error,com.caoccao.javet.exceptions.JavetExecutionException: Error: wrong number of arguments
testparam(1); //ok
testparam(1,2); //ok

what should I do?thanks
can I register a object like IJavetConverter to proxy V8FunctionCallback.receiveCallback for custom method invoke?

@V8Function on methods named 'get' are invoked with names of other methods as argument

Hi,

Still a big fan of this project ;-)

I noticed that Javet gets 'confused' when there is a method called get in the object that is being used in the scripting environment. Apparently this get method also gets invoked whit the name of the actual method that is being invoked prior to the invocation of the indented method.

I've reduced the example to the bare essentials. Hope this saves you some time...

The application contains a bean that implements a simple bookstore. This bean has a method inStock( String isbn ) to check if a particular book is in stock or not:

public class Bookstore() {
  @V8Function
  public boolean inStock( String isbn ) {
    System.out.println( "call Bookstore.inStock( '"+isbn+"')" ); // <- for debugging
    // ...finds the book on some shelf and then....
   return true;
  }

  // NOTE: The presence of the following method seems to confuse Javet...
  @V8Function
  public Book get( String isbn ) {
    System.out.println( "call Bookstore.get( '"+isbn+"')" ); // <- for debugging
    // ...well...
  }
}

The application exposes an endpoint at {host:port}/checkStock which expects a json-object that represents a book. The property we're after is accessible under book.isbn.

public boolean checkInStockThroughJavaScript( String isbn ) {
  // Create a Bookstore object that magically connects to the database!
  Bookstore bookstore = new Bookstore(); 

  // Prepare the script...
  String script = "bookstore.inStock( '"+isbn+"' );";

  try (engine = pool.getEngine() ) {
    // Add the bookstore to the runtime...
    runtime.getGlobalObject().set( "bookstore", bookstore);

    // Run the script and return the result...
    return runtime.getExecutor( script )..executeBoolean();

    // ...etc...
  }
  // ...etc, i know i should have cleaned up the bookstore...
}

When i run this i see an odd logging line on the console:

call Bookstore.get( 'inStock' )

Note that the method name is used as the parameter.

I sure hope this isn't 'as designed'...

Can't spawn an http server from node.js inside javet

I have a main.js file with this code:

const express = require("express");
const app = express();

app.listen(3000, "0.0.0.0", () => {
    console.log(`Running server`);
});

And from java I'm doing this:

  V8Host v8Host = V8Host.getNodeInstance();

  V8Runtime v8 = v8Host.createV8Runtime();
  v8.getExecutor(new File("main.js")).execute();
        
  Scanner in = new Scanner(System.in);
  System.out.println("running server, press enter stop");
  in.nextLine();

I dont get any errors but the server never starts either.

Also note that bukkit/spigot/paper servers (the platform I am using this on) do not immediately call the onLoad method. It calls this method when the plugin is first loaded onto the server, which can be at any time. I believe there may be some unique behavior in relation to the ClassLoader as well, but I am not 100% sure.

Empower JavetProxyConverter to Consume Some Annotations

• Refactor the doc to have dedicated section for individual converter.
• Add @V8Convert to class to provide proper config for JavetProxyConverter.
• Let JavetProxyConverter consume @V8Property at field level.
• Let JavetProxyConverter consume @V8Function, @V8Getter, @V8Setter, @V8Allow, @V8Block at method level.
• All changes applied to JavetProxyConverter are applied to JavetBridgeConverter.

Does using enginePool cause memory leaks？

I need to run v8runtime 100~1000 per second, use enginepool to initialize the instance, and load the lodash library in each v8runtime. When running at full speed, the console has a lot of warnings.
I have 2 questions:

1. Will continuous operation cause memory leaks?
2. How to release these objects in time?

Cannot create runtime : dll already loaded in another classloader

Hello,

I use Javet to run js build tools (eslint, babel...) in a maven plugin.

But when updating the project in eclipse, the maven plugin is reloaded and fails trying to create again the javet runtime with V8Host.getV8Instance().createV8Runtime(); :

Failed to read ....AppData\Local\Temp\javet\20964\libjavet-v8-windows-x86_64.v.1.0.5.dll - Native Library ...\AppData\Local\Temp\javet\20964\libjavet-v8-windows-x86_64.v.1.0.5.dll already loaded in another classloader

I think this fails because the dll is in the main classloader, where as the plugin has its own classloader.
Is there another way of retrieving a runtime without reloading the dll ?

V8Runtime.createV8ValueString() and V8Runtime.createV8ValueFloat()

I noticed these 2 methods seem to be missing, is this intended or maybe something that was overlooked?
