Subject [jira] Commented: (HARMONY-5364) [drlvm][jit]memory leak at init_helper_map at rt_helper_info.cpp while HWA run
Date Tue, 18 Mar 2008 08:07:24 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-5364?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12579755#action_12579755
] 

Pavel Pervov commented on HARMONY-5364:
---------------------------------------

Statics are not memory leak in general. When the module is unloaded, destructors for statics
are executed. This is most likely peculiarity of the tool that expects that upon exiting "main"
all data allocated during execution of main should be freed.

Anyway, fixing HARMONY-5505 I'm making this map environment local and its content will be
cleared during DestroyJavaVM. I'll update this JIRA as soon as HARMONY-5505 will be fixed.
