After I have patched the loadClassInternal in the rt.jar I am still
seeing the jboss lock up on deployment. Here are the two threads that
are actually doing something . I can see why CCRAPoll is hung because
the main thread has locked that classloader. But the "main" thread is
waiting to lock a classloader that is not locked. Is it possible that a
Jetty class is extending the UnifiedClassLoader and causing a deadlock?
Or are we seeing the same problem with java.net.FactoryURLClassLoader
