Subject [jira] Commented: (HARMONY-5159) [drlvm][jit] stress tests org.apache.harmony.test.stress.gc.frag.Fragmentation hung
Date Fri, 07 Dec 2007 10:33:43 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-5159?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12549365
] 

Evgueni Brevnov commented on HARMONY-5159:
------------------------------------------

AFAIU, there are two different problems. The first one relates to proper exception handling
(like OutOfMemroyException) by profiler/recompilation threads. This problem should be fixed
by JIT team. The second one is perfomrace degradation. I think the last problem should be
evaluated by some one with good knowledge in finalization system. 

Thanks
Evgueni
