Tim Fox commented on JBMESSAGING-1468:
--------------------------------------
Message copying is necessary when sending a message to DLQ or expiry queue.
This is because the same message can be sent to a topic with many subscribers. Each
subscriber can then expire or dlq the message at a different time, with different values
of properties.
If we didn't copy it that wouldn't work.
Eliminate message.copy on DLQ and Expire. Instead just creating a new
reference to the same message.

Key: JBMESSAGING-1468
URL: https://jira.jboss.org/jira/browse/JBMESSAGING-1468
Project: JBoss Messaging
Issue Type: Task
Reporter: Clebert Suconic
Assignee: Tim Fox
DLQ and Expire are copying Messages between queues, by assigning a new ID.
This will be a problem with LargeMessages. (Say if a message has 2G. The move will need
to copy a file around on the server file, and this could lead to timeouts since Expire
could be generated from the user side).
This would be a problem with replication also.
