According to JBMESAGING-526, if you receive a message and rollback it... Later on you receive the same message again in a different session, redelivery flag is not set. I have a question thoguth. When you call rollback explicitaly, shouldn't the message be sent back to the queue as the message never left the queue? I thought a redelivery flag would be set to true in case of failures, say a socket connection broken, or some other issue.
