JGroups leaks thread context classloader to internal
threads
------------------------------------------------------------
Key: JGRP-752
URL: http://jir
a.jboss.com/jira/browse/JGRP-752
Project: JGroups
Issue Type: Bug
Affects Versions: 2.6.2
Reporter: Brian Stansberry
Assigned To: Bela Ban
Attachments: classloader-leak.patch
Follow-up to discussion on the jgroups-dev list of issue
where threads created by JGroups, particularly pool threads,
inherit their TCCL from whatever thread triggers their
creation. This can leak application classloaders in an
environment where different applications share JGroups
resources.
Attached is a patch for this, against the 2.6 branch. We
can use this to discuss whether this is worth fixing in
JGroups. I have a fix in JBoss AS, although I'm concerned
it could prove fragile over time.
The patch is pretty simple, except for TCLAction, an
abstraction used to deal with the presence or absence of a
SecurityManager. I also tried to handle a J2ME case where
SecurityManager, or even the ClassLoader class, don't exist.
Not sure if that will work, just an effort.
Patch includes a unit test based on the one in JBoss AS.
Hasn't really been properly adapted to all the stuff going
on in the JGroups test environment, but it works.
