Incorporate MultithreadedTestCase (MTC) usage into JGroups testsuite
--------------------------------------------------------------------
Key: JGRP-693
URL: http://jira.jboss.com/jira/browse/JGRP-693
Project: JGroups
Issue Type: Task
Environment: JGroups testsuite test cases
Reporter: Richard Achmatowicz
Assigned To: Bela Ban
Fix For: 2.7
MultithreadedTestCase (MTC) is an open-source testing framework which supports the writing of multithreaded test cases. It introduces a global tick-counter which provides a deterministic form of thread synchronization, based on the number of times all threads in a test case are blocked. The tool works well ina debugger, unlike other approximate forms of synchronization (e.g. sleep())
This issue concerns using MTC in order to simplify and improve test cases in the JGroups test suite in which concurrency and blocking are at issue.

[JBoss JIRA] Created: (JBAS-4514) CLONE -Deadlock when logging trace

CLONE -Deadlock when logging trace
----------------------------------
Key: JBAS-4514
URL: http://jira.jboss.com/jira/browse/JBAS-4514
Project: JBoss Application Server
Issue Type: Bug
Security Level: Public (Everyone can see)
Reporter: chris effenberger
Assigned To: Scott M Stark
SourceForge Submitter: genman .
This was caused when trace was enabled. I imagine it
was caused by the classloader trying to load a class
while it was being rendered (?) to disk. Probably not
a big issue, unless trace-logging is enabled.
