findbugs's Issues

No bug search for classes inside of inner member classes

run findbugs on the followed class:

public class Test {
    private void testNamedInnerClass() {
        class B implements Runnable {
            public void run() {
                String s = null;
                s.equals(new Object() {
                    void test(){
                        String s = null;
                        s.equals(new Object() {

                        });
                    }
                });
            }
        }
    }

    private void testAnonymousClass() {
        Thread t = new Thread(new Runnable (){
            public void run() {
                String s = null;
                s.equals(new Object() {
                    void test(){
                        String s = null;
                        s.equals(new Object() {

                        });
                    }
                });
            }
        });
    }
}

AS IS:
NP bug ("Null pointer dereference") is reported only twice
TO BE:
there are 4 NP bugs.

The bugs inside of inner member classes (both named or anonymous) are not 
reported at all. It looks like FindBugs either ignores these classes 
during bug search or could not report bugs for.

Findbugs Html report

Hi ,

            I am generating FindBugs html reports on my source code. I am
using ant to do that. How to stop generating report, if there is nothing to
report

 Thanks in Advance

Bug instance occurrance number

There is a field edu.umd.cs.findbugs.BugInstance.instanceOccurrenceNum that only seems to take on the value of 0. What is the purpose of this field? What does it mean for a bug instance to have multiple "occurrences"? Should this field have a value other than 0?

P.S. I posted this issue here due to the dead sourceforge link.

Need to configure severity for FindBugs meesages in Problems view

At the moment MarkerReporter.java is using severity = WARNING so all
FindBugs issues will be displayed as warning messages in Problems view. It
would be great if I can configure FindBugs plugin to display issues as
error messages (i.e. IMarker.SEVERITY_ERROR)

False positive for Bad Cast

What steps will reproduce the problem?

Run FindBugs GUI on the "mail" module of Project GlassFish
(http://glassfish.dev.java.net).

There are several instances of code such as the following:

        if (message instanceof SMTPMessage)
            from = ((SMTPMessage)message).getEnvelopeFrom();


What is the expected output? What do you see instead?

Complains about an unchecked cast.

formatting of source code containing tabs is incorrect

What steps will reproduce the problem?

Run FindBugs GUI on the "mail" module of Project GlassFish
(http://glassfish.dev.java.net).  Select an error that
cauases source code to be displayed.


What is the expected output? What do you see instead?

Formatting of source code containing tabs is incorrect.
Tabs should be handled properly or expanded to 8-space
tab stops before display.  Prepending line numbers to each
line should not effect effect formatting but should push
all text to the right.

[Eclipse plugin] wrong classpath used to find bugs

AS IS:
In projects, which contains more then one class folder with generated 
classes (say one is the default one from Eclipse, another one is temporary 
created by ant during deployment task) FindBugs report bugs in both 
folders, even if some of folders are not on the class path of the project. 
This lead to duplicated time used to search bugs in Eclipse and to wrong 
bug markers generated (or to not generated at all).

TO BE:
FindBugs should search for bugs only in class folders which are on the 
classpath of Java project.

Using latest FindBugs build from SVN head with Eclipse 3.2.2 on JDK 1.5.

Patch (against head) which solves the problem is attached below.

Is `onlyAnalyze` option supported?

This manual said that we can use onlyAnalyze option, but I cannot find related classes in this project.

Is this problem of implementation, or manual? Is there any newer manual on the web?

Impossible cast from javax.naming.CompositeName to com.sun.jndi.dns.DnsName in compareRange(int, int, Name) in DnsName.java

Impossible cast from javax.naming.CompositeName to com.sun.jndi.dns.DnsName in

  393:       int minSize = Math.min(end - beg, n.size());
  394:       for (int i = 0; i < minSize; i++) {

Bug pattern explanation:
This cast will always throw a ClassCastException. FindBugs tracks type 
information from instanceof checks, and also uses more precise information 
about the types of values returned from methods and loaded from fields. Thus, 
it may have more precise information that just the declared type of a 
variable, and can use this to determine that a cast will always throw an 
exception at runtime.

Better support for lambdas/method references

To write new detectors involving lambdas/method references the following feature in the internal FindBugs engine is necessary: an ability to easily get for given invokedynamic call the lambda method name or referenced method descriptor (including constructor, bound or unbound method reference). To do this BCEL should be updated as current version does not parse all the necessary attributes.

As an additional feature it would be nice to add special support for Java 8 Stream API: ability for given Stream object get all the previous steps performed in that Stream if possible.

Bad attempt to compute absolute value of signed 32-bit hashcode in keyHash(Object) in KeyedHashSet.java

Bug report generated from FindBugs
Bad attempt to compute absolute value of signed 32-bit hashcode in 
keyHash(Object)

In class org.eclipse.core.internal.registry.KeyedHashSet
  In method keyHash(Object)
  At KeyedHashSet.java:[line 199]

Relevant source code:
  195:      return elementCount == 0;
  196:   }
  197: 
  198:   private int keyHash(Object key) {
  199:      return Math.abs(key.hashCode()) % elements.length;
  200:   }

Bug pattern explanation:
This code generates a hashcode and then computes the absolute value of that 
hashcode. If the hashcode is Integer.MIN_VALUE, then the result will be 
negative as well (since Math.abs(Integer.MIN_VALUE) == Integer.MIN_VALUE). 
One out of 2^32 strings have a hashCode of Integer.MIN_VALUE, including 
"polygenelubricants" "GydZG_" and ""DESIGNING WORKHOUSES".

Impossible downcast of toArray() result to org.eclipse.jdt.internal.corext.refactoring.typeconstraints.ITypeConstraint[] in create(SingleVariableDeclaration) in FullConstraintCreator.java

Impossible downcast of toArray() result to

  Return value of java.util.List.toArray()
  At FullConstraintCreator.java:[line 393]
Classified as: MOSTLY_HARMLESS
test evaluation
Bug pattern explanation:
This code is casting the result of calling toArray() on a collection to a type 
more specific than Object[], as in: 
String[] getAsArray(Collection<String> c) {
  return (String[]) c.toArray();
  }
This will usually fail by throwing a ClassCastException. The toArray() of 
almost all collections return an Object[]. They can't really do anything else, 
since the Collection object has no reference to the declared generic type of 
the collection. 
The correct way to do get an array of a specific type from a collection is to 
use c.toArray(new String[]); or c.toArray(new String[c.size()]); (the latter 
is slightly more efficient). 
There is one common/known exception exception to this. The toArray() method of 
lists returned by Arrays.asList(...) will return a covariantly typed array. 
For example, Arrays.asArray(new String[] { "a" }).toArray() will return a 
String 
[]. FindBugs attempts to detect and suppress such cases, but may miss some.

Add warning about using parallelStream/parallel/parallelSetAll in static initializer

The parallelStream/parallel/parallelSetAll calls in static initializer may cause deadlock when the stream pipeline or parallelSetAll call refer to the lambda function defined in the same class, because the operation might be performed in separate thread and will wait for class initialization to complete, but class initialization cannot be complete until the stream pipeline is executed.

Example:

import java.util.stream.IntStream;

public class StreamSum {
    static final int SUM = IntStream.range(0, 100).parallel().reduce((n, m) -> n + m).getAsInt();

    public static void main(String[] args) {
        System.out.println(SUM);
    }
}

Compile and launch this class. It will stuck in the deadlock on multicore system (but run correctly on single-core system).

how to configuration findbugs to support check third party jar?

My project is type of android.

ActivityManager manager = (ActivityManager)this.getSystemService("");
List services = manager.getRunningServices(Integer.MAX_VALUE);

The object "services" maybe null,but it is a part of android.jar,so findbugs don't check the return value.

what the mean of "auxClasspath"?

Thank you in advance.

FP with BC (instanceof always returns true)

I would hope that this is not a common design, and so perhaps you don't fix
it, but here's a false positive for BC (instanceof always returns true).
This is a simplified version, but i wasn't sure whether the code i found
was intending on the code to always be initialized. I suppose the test
should just be changed to, == null.. but...

public class BC_FP {
    private List l;

    public void setList(ArrayList ll) {
        l = ll;
    }

    public void fp() {
        if (l instanceof ArrayList) {
            System.out.println("FP - what if l is null?");
        }

Impossible downcast of toArray() result to org.eclipse.jdt.internal.corext.refactoring.typeconstraints.ITypeConstraint[] in create(SingleVariableDeclaration) in FullConstraintCreator.java

Bug report generated from FindBugs
Impossible downcast of toArray() result to 
org.eclipse.jdt.internal.corext.refactoring.typeconstraints.ITypeConstraint[] 
in create(SingleVariableDeclaration)

In class 
org.eclipse.jdt.internal.corext.refactoring.typeconstraints.FullConstraintCreato
r
  In method create(SingleVariableDeclaration)
  Actual type Object[]
  Expected org.eclipse.jdt.internal.corext.refactoring.typeconstraints.ITypeConstraint[]
  Return value of java.util.List.toArray()
  At FullConstraintCreator.java:[line 393]
Classified as: MOSTLY_HARMLESS
test evaluation
Bug pattern explanation:
This code is casting the result of calling toArray() on a collection to a type 
more specific than Object[], as in: 
String[] getAsArray(Collection<String> c) {
  return (String[]) c.toArray();
  }
This will usually fail by throwing a ClassCastException. The toArray() of 
almost all collections return an Object[]. They can't really do anything else, 
since the Collection object has no reference to the declared generic type of 
the collection. 
The correct way to do get an array of a specific type from a collection is to 
use c.toArray(new String[]); or c.toArray(new String[c.size()]); (the latter 
is slightly more efficient). 
There is one common/known exception exception to this. The toArray() method of 
lists returned by Arrays.asList(...) will return a covariantly typed array. 
For example, Arrays.asArray(new String[] { "a" }).toArray() will return a 
String 
[]. FindBugs attempts to detect and suppress such cases, but may miss some.

Heap space issue

I currently am running findbugs 1.3.9, and am running into a heap space issue. 
This I do not believe is any ordinary heap space issue. Like other heap space 
issues, you can simply increase the heap space through the Xmx arg, the only 
problem is I have -Xmx2500M which is I believe too much. I am also running 
findbugs on effort=max. Which I know consumes more memory, but I don't believe 
it needs this much memory. The .jar I'm scanning is 15MB if that is significant.

Here is a sample output:

DMI_ANNOTATION_IS_NOT_VISIBLE_TO_REFLECTION

original report 26 July 2006 by Ruimo Uno (Shisei Hanai)
--------
Hi,

The DumbMethods detector in FIndBugs-1.0.0 reports the
DMI_ANNOTATION_IS_NOT_VISIBLE_TO_REFLECTION against the following
code:

Method m = String.class.getMethod("getBytes", new Class[] {int.class,
int.class, byte[].class, int.class});
if (m.isAnnotationPresent(Deprecated.class)) {

Since the retention policy of the @Deprecated is the RUNTIME, this is a false
positive. It seems that the DumbMethods uses a retention class database that
is set by the visitAnnotation(). As a result, FindBugs can report correctly
only
for visited annotation classes and other classes are wrongly reported as bugs.
Is this as designed?

32 bit int shifted by 56 bits in read8(RandomAccessFile) in IconExe.java

Bug report generated from FindBugs
32 bit int shifted by 56 bits in read8(RandomAccessFile)

In class org.eclipse.equinox.internal.p2.swt.tools.IconExe
  In method read8(RandomAccessFile)
  Shifted by 56 bits
  Local variable named b7
  At IconExe.java:[line 703]

Relevant source code:
  699:       int b4 = raf.readByte() & 0xFF;
  700:       int b5 = raf.readByte() & 0xFF;
  701:       int b6 = raf.readByte() & 0xFF;
  702:       int b7 = raf.readByte() & 0xFF;
  703:       return b7 << 56 | b6 << 48 | b5 << 40 | b4 << 32 | b3 << 24 | b2 << 16 | b1 << 8 | b0;

  706:      raf.write(value & 0xFF);
  707:      raf.write((value >> 8) & 0xFF);

Bug pattern explanation:
The code performs shift of a 32 bit int by a constant amount outside the range 
0..31. The effect of this is to use the lower 5 bits of the integer value to 
decide how much to shift by (e.g., shifting by 40 bits is the same as shifting 
by 8 bits, and shifting by 32 bits is the same as shifting by zero bits). This 
probably isn't want was expected, and it at least confusing.

findbugsTestCases from branch 1.3.9 reports bugs as expected, findbugsTestCases from rev. 13120 reports no bugs

Reproduction steps:
1. check out rev. 13120 and version 1.3.9 of findbugs
2. on each, perform: cd findbugsTestCases; ant

select output from 1.3.9:

I ran this w/ ant v. 1.8.1; java 1.6_22 on linux kernel version 2.6.36, 64bit 
userspace.

I encounter this non-reporting problem when using a rev. 13120 findbugs-ant.jar 
on my own projects.  I expect that specifying "<findbugs ...  reportLevel="low" 
..." will cause findbugs to report all bugs found.  Nonetheless, when 
TextUiCommandLine lns. 584-5 are executed, they set a rankThreshold and 
priorityThreshold that cause two of my test case 
bugs--ST_WRITE_TO_STATIC_FROM_INSTANCE_METHOD and 
URF_UNREAD_PUBLIC_OR_PROTECTED_FIELD--to fail the test at ln. 175 of 
AbstractBugReporter and thus they are not reported.

Further, I can see that only a small subset of available detectors are ever 
applied to my classes (the ones in detectorList, which is populated in ln. 1039 
of FindBugs2).  I expected that all detectors in edu.umd.cs.findbugs.detect 
would be applied if I didn't specify an inclusion or exclusion list.  It looks 
like a lot more detectors (some 155) are added to a plugin's 
detectorFactoryList , but I'm not clear on the intended use of that list and 
the later-populated detectorList.

Unexpected warning about dereferencing without a null check

I figured a quick example repo would be the easiest way to describe the problem:

https://github.com/djeikyb/borken_findbugs

In short, I don't expect findbugs to complain about the call to getFileName() on the second line not being sufficiently null checked.

if (p.getFileName() == null) return;
String s = p.getFileName().toString();

In case it's useful, I included the build artifacts after running mvn clean compile findbugs:findbugs (class files, findbugs report),

Used java 1.8 with findbugs 3.0.2, same results on linux and osx

not calling checkError when using java.io.PrintWriter and java.io.PrintStream should be flagged

In javadocs for java.io.PrintStream 
(http://java.sun.com/j2se/1.4.2/docs/api/java/io/PrintStream.html)

"Unlike other output streams, a PrintStream never throws an IOException; 
instead, exceptional situations merely set an internal flag that can be tested 
via the checkError method. "

similar for java.io.PrintWriter.

Perhaps findbugs should warn when calling write and not checking the error 
status.

filepath lookup for filters

What steps will reproduce the problem?
1. in .fbprefs, set excludefilter0 to filepath, eg
=c:/myproject/findbugs-exclude.xml
2. refresh eclipse project

What is the expected output? What do you see instead?

Expected output is
1) to have the filter taken into account and 
2) to see in the project properties -> findbugs page
c:/myproject/findbugs-exclude.xml

Actual output is
1) filter not taken into account, I assume it searches only in the
classpath, not filesystem
2) project properties -> findbugs page shows /myproject/findbugs-exclude.xml

(it does work when filter file placed in same dir as project (so in
multi-module system you need to copy them all over to make the plugin work)

What version of the product are you using? On what operating system?
v1.3.8.20090111
OS=WinXP

Eclipse plugin can allocate virtually unlimited amount of resources

I'm using Eclipse to work on ~1MLOC application consisting of a dozen of Eclipse projects.
When I switch a branch (for example from a WIP branch to master) Eclipse can determine that most classes need to be recompiled. When that happens, FindBugs Eclipse plugin dispatches analysis on all affected projects, running multiple analysis jobs at once (as observed in Progress view).
Since each analysis job seems to take 1 CPU and lots of memory, this renders Eclipse unusable for several minutes (it's even very hard to manually interrupt those jobs in the progress view).

A workaround is to select 'run findbugs as part of build' -- but then build takes minutes (so many that I don't know how many).

I think the plugin should be more modest in allocating resources. Ideally, FindBugs should run as a subprocess (with nice perhaps). If that's not possible, it should not use all CPU and memory that is available to Eclipse. Like "use only half of CPUs and not more than ?? memory". At least, number of concurrent analysis should be configurable, if sensible default is not to be guessed.

False Positive on "Dls dead local store"

Hi there! It appears i have a false positive on this warning. In my Android project, I try to make a file where i'm going to store some profile pictures. I'm doing this on a singleton service, inside a static method:

private static File createCameraImageFile() throws IOException {
        final String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault()).format(new Date());
        final String cameraPhotoFileName = String.format("UMW_PROFILE_%1$s.jpeg", timeStamp);
        final File storageDir = Environment.getExternalStoragePublicDirectory(
                Environment.DIRECTORY_PICTURES);
        return new File(storageDir, cameraPhotoFileName);
    }

The warning says I have a dead local store on cameraPhotoName. I tried deleting the variable and just put it directly in the return, like this:

private static File createCameraImageFile() throws IOException {
        final String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault()).format(new Date());
        final File storageDir = Environment.getExternalStoragePublicDirectory(
                Environment.DIRECTORY_PICTURES);
        return new File(storageDir, String.format("UMW_PROFILE_%1$s.jpeg", timeStamp));

But it would point out that i have a dead local store in timeStamp. Its seems that it doesnt like local variables! Thank you very much! Cheers

Missing dep in Maven artifact for FB annotations

See http://netbeans.org/bugzilla/show_bug.cgi?id=199560#c4 for background. I am 
not sure who uploaded 1.3.9 to Maven Central, but the POM for the annotations 
JAR is incorrect; it fails to refer to the JSR 305 JAR, which is a compile-time 
dependency. JDK 6 javac can crash as a result.

By the way - it seems that development is now happening on 
code.google.com/p/findbugs, yet findbugs.sourceforge.net makes no direct 
mention of this (and still has an open issue tracker with recent additions).

[Eclipse plugin] Exceptions and missing line info for inner member classes and for fields

This is a cumulative patch/bug report for 3 issues.

1) AS IS: Bugs which are in inner *member* classes (*named* classes which 
are declared inside of method body of another class) leads to 
NumberFormatExceptions in FindBugs plugins, so that they are not reported 
and not visible in Eclipse at all.

Exemple from Eclipse log:

java.lang.NumberFormatException: For input string: "1MyRunnable"
at java.lang.NumberFormatException.forInputString(NumberFormatException.jav
a:48)
at java.lang.Integer.parseInt(Integer.java:456)
at java.lang.Integer.parseInt(Integer.java:497)
at de.tobject.findbugs.reporter.MarkerUtil.findChildSourceLine(MarkerUtil.j
ava:249)
at de.tobject.findbugs.reporter.MarkerUtil.completeInnerClassInfo(MarkerUti
l.java:195)
at de.tobject.findbugs.reporter.MarkerUtil.getUnderlyingResource(MarkerUtil
.java:176)
at de.tobject.findbugs.reporter.MarkerUtil.createMarker(MarkerUtil.java:93)
at de.tobject.findbugs.reporter.Reporter.doReportBug(Reporter.java:111)

TO BE: no exception, bug is propely reported


2) AS IS: Bug markers which are in inner classes are not always shown in 
editor, because FindBugs plugin may use -1 as a source location (if the 
line was not reported in the bug), so that Eclipse shows the bug in the 
Problems view but not in the editor (editor lines starts with 1).

TO BE: bug is propely reported in editor too

3) AS IS: Bug markers for fields which shown in the Problems view are 
never at the right location in the editor, because this info is not 
available in the bug instance.

TO BE: bug is propely reported in editor too

Seen with the latest FindBugs from SVN with Eclipse 3.2.2 and JDK 1.5

Please use the patch attached below to fix all three problems.

[prefs] Improve diff/versioning of preferences file (patch)

Hi,
I've already sent an email with this patch to Bill Pugh, but probably my 
mail was filtered as spam (I haven't received any answer), so I've decided 
to post this patch here.

Patch to UserPreferences class:

we hold all project preferences in VCS, so that we could esily track any 
changes. Unfortunately the current FindBugs .fbprefs file is baked by 
Property class. This means that each time you add/remove a key, the key 
order may be randomly changed for *all* other keys too. Another problem is 
the *format* of the key elements for detector enablement. Current format 
is "detector<Number>", where <Number> is just a position of detector in 
the iterator, created by iterator over property file, which returns 
*random* numbers for the same detector each time you store the values.

Old example:

#FindBugs User Preferences
#Mon Dec 04 23:52:02 CET 2006
detector0=SluggishGui|true
detector100=AbnormalFinallyBlockReturn|true
detector101=IncompatMask|true

AS IS: removing "SluggishGui" detector would change the key names for 
AbnormalFinallyBlockReturn and IncompatMask, so that all three lines in 
the porperty file would be marked as changed by diff tool.

TO BE: it would be nice to have a preferences where changes of *one* 
detector setting would lead only to *one* line change compared to previous 
state.

My patch changes the key creation shema and allows the Property file be 
always stored in a sorted state to the disk. Both changes together 
guaranteed you the requirement above.
My patch is compatible to already existing .fbprefs files.

Regards,
Andrei Loskutov

The version of bcel used in the trunk is not clear from the file name, nor is it stated in the manifest of bcel.jar

What steps will reproduce the problem?
1. Checkout the code svn checkout http://findbugs.googlecode.com/svn/trunk/
findbugs-read-only
2. Look in findbugs/lib
3. There is a bcel.jar file without a version number in the file name.
4. Look in the bcel.jar file 
$ jar xf bcel.jar META-INF
$ cat META-INF/MANIFEST.MF 
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.0
Created-By: 1.5.0_16-133 (Apple Inc.)

Expected: The version of the BCEL library being used.
Actual: No version number in either the file name or the Manifest.

I need the version so I may follow the code that makes use of BCEL classes
when writing my own detector, to see for example what methods are available
in InvokeInstruction when stepping through the code.

There is a workaround, which is to just replace bcel.jar with the latest
stable release of bcel from the apache website. But it's not ideal. Better
make the project plug and play by ensuring the dependencies to third party
libraries are clearly versioned.

  707:      raf.write((value >> 8) & 0xFF);

Bug pattern explanation:
The code performs shift of a 32 bit int by a constant amount outside the range 
0..31. The effect of this is to use the lower 5 bits of the integer value to 
decide how much to shift by (e.g., shifting by 40 bits is the same as shifting 
by 8 bits, and shifting by 32 bits is the same as shifting by zero bits). This 
probably isn't want was expected, and it at least confusing.
