>             Project: Harmony
>          Issue Type: Bug
>          Components: DRLVM
>         Environment: Windows XP i686

> 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.
