Any good resource on JBoss5.1 class loading

Question

I'm debugging a thorny CL-related problem and need a better understanding of how classloading works in JBoss 5.1.

Yes, I read http://community.jboss.org/wiki/JBossClassLoaderIntroduction and http://community.jboss.org/wiki/JBossClassLoaderOverviewandGoals; they are useful to start with, but are not very precise in their description. The "main page" at http://community.jboss.org/wiki/JBossClassLoading is not particularly rich in detail.

Any other recommended resources ?

Thanks in advance.
