Hi Kabir,
Ive tried it against a HEAD build and still get the same problem.. strace follows

Snapshotfeed is the superclass of Snapshotfeed$$Proxy$$ neither are on the classpath as they are being downloaded across the network.
Ill put a testcase together for this...
Thanks
Neil.

On further thought I realise that this wont work....We are create a remote-proxy on an object by generating the bytecode which subclasses the class of interest to which we then apply a remoting aspect. When this $Proxy$ class comes across the wire, looking up the superclass will fail as it doesnt exist.
I suspect this is going to be the case for any network based classloader which jboss-aop is weaving. The networked class wont exist on the classpath so it would make sense for jboss to call back onto the defining classloader to request the super. This would allow for the super also be downloaded and defined... (instead of relying on the sytem classloader).

Hi Kabir,
We need to integrate our classloader env with Javassist using (ClassPath.appendClassPath(new ClassClassLoader(this))). We then we ran into a classloader related deadlock which was due to part of a classloaderimpl being aspectized. Removing that sorted out the deadlocking and now it all works properly.

Thanks for you help.
-Neil.
