Description

When sending any ObjectMessage that contain an equal object to was been sent before I get from KahaDBStore : Duplicate message add attempt rejected.

So even if the messageId and commandId is different the message is still detected as a duplicate and ignored.

A simple test would be to create two objectmessages with "session.createObjectMessage("ANY OBJECT THAT is Equal")" and send to a queue.

Our code worked with version 5.7.0 and tested amq-store as well as KahaDbstore.
