Subject [jira] Updated: (HARMONY-2697) [drlvm] Un-end()-ed deflaters leak native memory
Date Wed, 16 May 2007 13:24:16 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-2697?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

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.

>                 URL: https://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
> in native heap. The native heap is exhausted before java heap is filled, so no garbage
> occurs. Should the java collection occur, it would be able to detect unreachable finalizable
> run finalizers, which in turn will free native memory.
