> RpcDispatcher is hard-coded to use JGroups' classloader when marshalling the users's custom objects over RPC.
> RpcDispatcher uses Util.objectFromByteBuffer to unmarshall, which uses an ObjectInputStream.  ObjectInputStream uses the classloader of its caller's class (Util).
> RpcDispatcher does allow a custom marshaller to be used (implementing RpcDispatcher.Marshaller), but since Util.objectFromByteBuffer hard-codes the use of ObjectInputStream, a custom marshaller cannot simply set the classloader and then delegate back to the default JGroups code.
> Util.objectFromBuffer should be enhanced to use a custom ObjectInputStream implementation that overrides resolveClass to use a custom classloader, and an API should be added to RpcDispatcher to pass in the classloader to use.
