[jira] Commented: (HARMONY-3892) [drlvm][thread] Deadlock during thread creation from custom sytem classloader

["Pavel Pervov (JIRA)" <ji...@apache.org>]

Pavel Pervov commented on HARMONY-3892:
---------------------------------------

This is the deadlock between ClassLoader0 and ClassLoader0 which occurs through thread starting code.

_alarmThread.start() calls Thread.lock.wait() inside synchronized ClassLoader0 and waits until target thread is started. Thread starting code calls to FindClass("java/lang/Thread") which in turn calls to ClassLoader0.loadClass.

Looks like I know the way. :) Will try to fix fast.
