[jboss-jira] [JBoss JIRA] (JGRP-1410) globalThreadGroup not destroyed creates a classloader memory leak
[

]
Bela Ban resolved JGRP-1410.
----------------------------
Resolution: Done
I removed the use of ThreadGroup, as suggested in my prev comment. I also fixed a bug that
caused timer threads to have a null or <ADDR> cluster name when a shared transport
was used.
Let me know if this fixes your classloading leak, and re-open if the leak still exists.
globalThreadGroup not destroyed creates a classloader memory leak
-----------------------------------------------------------------
Key: JGRP-1410
URL: https://issues.jboss.org/browse/JGRP-1410
Project: JGroups
Issue Type: Bug
Affects Versions: 3.0.1
Environment: linux w/ java 1.6
Reporter: Jean-Philippe Gariepy
Assignee: Bela Ban
Fix For: 3.3
When all channels are closed, the globalThreadGroup is not destroyed. For a normal (i.e.
non-web) application, this is not a problem since the process will exit anyway. However,
for a Java Enterprise web application, this causes a classloader memory leak since the
ThreadGroup object has strong references to JGroups instances having strong references to
their class object having strong reference to their class loader. Since the class loader
is pointed by strong references, the it cannot be garbage collected and hence a leak is
created each time the web application is stopped.
