i would say that we have a deadlock issue when one thread is using jbossaop classloader and another is using the default one ( eg not the jbossaop classloader). if all threads are using the jbossaop classloader we shouldnt see this error (i hope). i havent had the time to look more deeply into this im afraid, if i got some spare time ill look a bit at it during the weekend, but i wont promise anything...
