When you get stack traces with this in it:

java.lang.NullPointerException
 at org.jboss.mx.loading.RepositoryClassLoader.findClass(RepositoryClassLoader.java:623)

It usually means that JBoss's classloader has got itself into an unrecoverable state, and the loading of certain core classes fails, which occasionally happens after a lot of hot deployments.

In my experience, it is usually fixed by a JBoss restart.
