[jboss-jira] [JBoss JIRA] Updated: (JBMESSAGING-1643) Ordering Group incorrect handling on Consumer close

[Howard Gao (JIRA)]

Howard Gao updated JBMESSAGING-1643:
------------------------------------

        Summary: Ordering Group incorrect handling on Consumer close  (was: Ordering Group incorrect handling on Session close)
    Description: 
On session close, all unacknowledged messages will be cancelled. For ordering group messages, if messages are cancelled, it will be redelivered first.
But currently if the message is cancelled, the message is released from the ordering group control, making the second message being delivered. That's broken.

The reason for the wrong order of delivery:

1. msg A is delivered and commited. then B is delivered to client.
2. consumer close() cause B cancelled back to queue. But it is wrongly removed from the linked list.
3. On next deliver, B cannot be delivered because it is not the first in the ordering group (B still an ordering group message). So C is delivered to client.
4. After C is committed, D is delivered to the client and committed.
5. then B is delivered as the whole ordering group is empty now.
