[jira] Created: (HARMONY-2697) [drlvm][zip] Un-end()-ed deflaters
leak native memory
[drlvm][zip] Un-end()-ed deflaters leak native memory
-----------------------------------------------------
Key: HARMONY-2697
URL: http://issues.apache.org/jira/browse/HARMONY-2697
Project: Harmony
Issue Type: Bug
Components: DRLVM
Environment: Windows XP i686
Reporter: Salikh Zakirov
Priority: Minor
Attachments: DeflateInflate.java
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.

The issue is still reproducible May 22 on Windows/x86 like:

java version "1.5.0"
pre-alpha : not complete or compatible

[jira] Commented: (HARMONY-2697) [drlvm] Un-end()-ed deflaters leak

Mikhail Markov commented on HARMONY-2697:
-----------------------------------------
I've linked this isssue with HARMONY-2530 which looks very similar.
The only problem is that 2530 is reproducible on J9 as well (while this JIRA report says that it reproducible on DRLVM only) - that's why i've linked them as "reated" not "duplicated".
Nevertheless i think that fixing 2530 will resolve this issue as well.

-------------------------------------------
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

[jira] Updated: (HARMONY-2697) [drlvm] Un-end()-ed deflaters leak

Gregory Shimansky updated HARMONY-2697:
---------------------------------------
Summary: [drlvm] Un-end()-ed deflaters leak native memory (was: [drlvm][zip] Un-end()-ed deflaters leak native memory)
I removed [zip] category because it doesn't fully describe the problem of large native resources associated with java objects.
