The test ClientProxyTest.testSimpleWebBeanClientProxyIsSerializable fails when run in a container due to classloader issues. Javassist is trying to use its own classloader, which in JBoss AS is a server classloader, to load the class loaded by the WAR classloader. The correct classloaders need to be setup with Javassist in order for persistence to work.

Current error in the server is:
