QueueEntries can hold the Subscriptions which rejected them in memory after they are closed
-------------------------------------------------------------------------------------------

                 Key: QPID-3387
                 URL: https://issues.apache.org/jira/browse/QPID-3387
             Project: Qpid
          Issue Type: Bug
          Components: Java Broker
    Affects Versions: 0.10, 0.9, 0.8, 0.7, 0.6, 0.5, 0.11, 0.12
            Reporter: Robbie Gemmell
            Assignee: Robbie Gemmell
             Fix For: 0.13


QueueEntries can hold Subscriptions which rejected them in memory after they are closed, due
to the implementation of the isRejectedBy() method. This is further compounded by the Subscriptions
having a reference to the channel/session they belong to, which in the case of a 0-10 ServerSession
can be an extremely heavy weight object in the wrong conditions. The isRejectedBy() implementation
should be updated to function without requiring a reference to the Subscription itself, thus
preventing the retention leak.

I have had a simple patch for this for a while, its just waiting for QPID-3336 being done
(which it almost is, will get it committed shortly).
