[esb-issues] [JBoss JIRA] Commented: (JBESB-1215) DBMessageStoreImpl not able to deserilize objects due to what appears to be a classloader/scoping issue

Kevin Conner commented on JBESB-1215:
-------------------------------------

Having checked the codebase the fix appears to be as simple as using the correct Base64 class.  Our version already uses the new class in place of ObjectInputStream.

Tom, do you want to take this and see?  It would be quicker than Kurt reproducing it.

> 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.
