RpcDispatcher Errors
I am getting the below exception when running a clustered application using JBoss 4.0.1, no idea why. It doesn't appear to be coming from my application code, although I am calling a QueueSession.commit() when sending as message in an EJB which might be causing this to happen (can't tell from the below exception), but the QueueSession is transacted so I don't think so. Also I am not doing anything with a TreeCache in my codes.

Any ideas on where this might be coming from, and what problem it indicates ?
Thanks in advance for any suggestions.
