Vladimir Beliaev commented on HARMONY-2697:
-------------------------------------------

Mikhail is right - attached DeflateInflate test has passed both with J9 & DRLVM on M4 revisions:

$ ~/trunk/working_classlib/deploy/jdk/jre/bin/java -cp . DeflateInflate
....................................................................................................PASSED
$ ~/trunk/working_vm/build/deploy/jdk/jre/bin/java -cp . DeflateInflate 
....................................................................................................PASSED

This bug may be closed as a DUPLICATE of HARMONY-2530.

Thanks
Vladimir

> The attached test DeflateInflate.java quickly leaks memory and crashes on DRLVM.
> The test works okay on J9 and HotSpot.
> Note, that JRockit also leaks memory and crashes.
> Effectively, the test creates huge amounts of java objects, which keep pointers to blocks allocated
> in native heap. The native heap is exhausted before java heap is filled, so no garbage collection
> occurs. Should the java collection occur, it would be able to detect unreachable finalizable objects,
> run finalizers, which in turn will free native memory.
