DBMessageStoreImpl not able to deserilize objects due to what appears to be a classloader/scoping issue
-------------------------------------------------------------------------------------------------------

                 Key: JBESB-1215
                 URL: http://jira.jboss.com/jira/browse/JBESB-1215
             Project: JBoss ESB
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Message Store
    Affects Versions: 4.2.1 IR2
            Reporter: Tom Fennelly
         Assigned To: Kurt Stam
             Fix For: 4.2.1 triage


I see this issue when running the deadletter quickstart.

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.

Here's the stack trace I see...
