Subject [jira] Commented: (HARMONY-3582) [drlvm][shutdown][thread] gc.Multithread smoke test hangs on Windows
Date Fri, 26 Oct 2007 17:20:52 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-3582?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12538027
] 

Rana Dasgupta commented on HARMONY-3582:
----------------------------------------

Hmmm...this is a good shutdown test, but does not really match the original bug where a daemon
thread was getting terminated inside a critical region, causing the shutdown thread to hang.
But it is true, that I have not seen this bug reproduced for a long time. So I am OK with
closing the bug. We can reopen it if we see it again.

Thanks,
Rana

I can repro the hang in the debugger as well. Breaking in with the debugger shows a deadlock
where the shutdown thread is blocked trying to acquire a critical section that was probably
not cleanly released by a terminated thread.
