Gary Tully commented on AMQ-5055:
---------------------------------
I have often wondered about the usecase but have concluded that the id is
implicit in the resend. If the id is changed it is a resend copy type op. So
not the same message. Duplicate detection is based on the id.
Maybe a unit test of the doresend op will help clarify. To my mind a resend
that results in a duplicate is an error. But I would expect a resend to
rollback the audit as appropriate.

> Using the webconsole copy option for a persistent message to copy the message
> more than once to the same destination queue leads to problems.
> The second copy of the message will increase the Queue size and enqueue
> counter, but does not actually place a message in the Queue, whether or not
> the earlier copy is still in the Queue. In addition, the following error
> message is logged by the broker.
> {noformat}
> WARN | duplicate message from store

> redirecting for dlq processing
> {noformat}
> Note that this was not tested across broker restarts. Non-Persistent
> messages do not appear to have this problem.
> It seems that maintaining the message ID across copies is causing problems.
> Creating a completely new message ID should be the simplest solution.
> Perhaps storing the original message ID in a property (e.g.
> JMSXSourceMessageId) on the new message would be useful in case anyone wants
> to be able to detect the copy and determine from which message it was created.
