             Summary: Broker allows the creation of duplicate queue entries on a single queue which then fail on-dequeue.
                 Key: QPID-4647
                 URL: https://issues.apache.org/jira/browse/QPID-4647
             Project: Qpid
          Issue Type: Bug
    Affects Versions: 0.20, 0.18, 0.16, 0.14, 0.12, 0.10, 0.21
            Reporter: Keith Wall


Using the copyMessage function, it is possible to cause a single message to appear _twice_ on a single queue. When a consumer consumes the duplicate and tries to acknowledge the duplicate, the Broker produces the following error. It is also possible to create the same situation using certain dead-letter arrangements.
