[jboss-user] [Installation, Configuration & Deployment] - How patch JBoss AS 5.1 with JBoss Classloader 2.0.6.SP1 - Fi

[timlambertmf]

I've been trying to install the patch associated with:
https://jira.jboss.org/jira/browse/JBCL-109

It fixes a hang in the classloader that I think we are hitting because we see all the HTTP threads blocked on a thread that look exactly like the stack in:
https://jira.jboss.org/jira/browse/JBAS-6327 

I tried using the -Djboss.patch.url method, but classes in the old jars seem to be getting loaded instead of the new ones.

I tried replacing the jars in jboss_home/lib with the JBCL 2.0.6.SP1 version:
http://repository.jboss.com/maven2/org/jboss/cl/jboss-cl-dist/2.0.6.SP1/

When I did the latter, JBoss AS 5.1 threw the following error at boot time trying to parse classloader.xml.

Any ideas?  What should the process be for installing such a patch?
