-------------------------------------

Thanks Kurt, that sorted that for the deadletter quickstart.  I see another issue now in the JMSEpr - will log that in a bit.

> DBMessageStoreImpl is trying to deserialize org.jboss.internal.soa.esb.message.format.serialized.MessageImpl through Base64.decodeToObject (actually, I guess it could be could be some other class that has MessageImpl as a property, but I doubt that).  Base64.decodeToObject uses ObjectInputStream, which resolves the class using the "latestUserDefinedLoader".  Not sure what that is coz latestUserDefinedLoader is a native method and the javadoc means nothing to me :-)  Whatever latestUserDefinedLoader is, it's not the TCCL coz I added test code to DBMessageStoreImpl and it's able to load the class through the TCCL.
