Subject [jira] Commented: (HARMONY-2963) [drlvm][stress] MegaSpawn test from HARMONY-2803 hangs in the end on dead lock
Date Thu, 11 Jan 2007 12:47:27 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-2963?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12463883
] 

Salikh Zakirov commented on HARMONY-2963:
-----------------------------------------

Reproduced the hang of MegaSpawn on single processor Windows XP.
The two threads are deadlocked on a shutdown:

Thread 1: jthread_wait_for_all_nondaemon_threads();
Thread 2: wait on java/lang/FinalizerThread$FinalizerWorkLock

Thread library has lib->nondaemon_thread_count = 230, meaning that
threads terminated by OOM did not correctly decreased non-daemon thread count.

> When running MegaSpawn test from HARMONY-2803 on windows and linux, if this test doesn't
kill VM, it hangs at the end in some dead lock of 2 or more threads. This bug doesn't seem
to be related to the stressing nature of the test, so it should be something different. It
is likely that this is the same IO dead lock which makes stress.Mix to hang when it is running
from "build test".
