Subject [jira] Commented: (HARMONY-2963) [drlvm][stress] MegaSpawn test from HARMONY-2803 hangs in the end on dead lock
Date Thu, 11 Jan 2007 15:06:27 GMT

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

moved-non-daemon-thread-count-modification-from-start-to-wrapper_proc.patch

The attached patch provides a fix for incorrect non-daemon thread count modifications
by moving the increment to the place where we are sure the thread is already started (and
also matches counter decrement better, because
counter is decremented in jthread_detach() on the target thread).

> 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".
