serkan-ozal / jillegal Goto Github PK

Hi,
After previous issue, I made some tests and now I getting other mysterious errors.

At each run I'm randomly getting or exception

Exception in thread "main" java.lang.AbstractMethodError: tr.com.serkanozal.jillegal.offheap.pool.impl.ComplexTypeArrayOffHeapPool.getAt(I)Ljava/lang/Object;

    at samples.OneMillionObjects.readRandomValues(OneMillionObjects.java:48)

Hi Serkan Ozal

You mentioned there's an issue with Parallel GC and jillegal library, but did not mentioned any details.

I had a similar project and observed crashes during the GC cycle with Parallel GC, and I believe this is the same issue. Can you share any experience you had with this issue?

It's not an issue, rather a question: I,m trying to make offheap object, that contains offheap array

@JillegalAware
public class HashVO extends DefaultVO {
    private HashVONode[] voarray;
    public void init(){
        OffHeapService offHeapService = OffHeapServiceFactory.getOffHeapService();

        arrayPool = offHeapService.createOffHeapPool(
                new ArrayOffHeapPoolCreateParameterBuilder<HashVONode>().
                        type(HashVONode.class).
                        length(10000).
                        initializeElements(false).
                        build());

        //this.voarray = arrayPool.getArray();
        setVoarray(arrayPool.getArray());

    }

    public void setVoarray(HashVONode[] voarray){
        this.voarray = voarray;
    }}

When I allocate it on heap - everything works fine, but when I trying to get it as offheap object

        EagerReferencedObjectOffHeapPool<HashVO> map_pool =
                offHeapService.createOffHeapPool(
                        new ObjectOffHeapPoolCreateParameterBuilder<HashVO>().
                                type(HashVO.class).
                                objectCount(10).
                                referenceType(ObjectPoolReferenceType.EAGER_REFERENCED).
                                build());
        HashVO hv = map_pool.get();

I'm getting JVM crash

I think that I'm doing something wrong, but can't figure out what.

Thanks in advance
PS Is there some doc available? 

https://github.com/serkan-ozal/jillegal/blob/master/src/main/java/tr/com/serkanozal/jillegal/Jillegal.java#L20

in the comment of last issue, you said
However there are some problems for offheap part of project due to compact phase of GC.
These problems can be handled by VM arguments but i am working on a better solution.

I do have a problem when testing offheap demo.
How to solve this problem?

Used memory on heap before On-Heap allocation: 1017992 bytes
Array for class with size 10000000 for class test.OffHeapDemo$SampleClass has be
en allocated ...
