>
> If a JMS user continually closes consumers on the same transactional session,
> a memory leak occurs at the following location. The leak remains until the
> Session is closed ({{Session#close()}}) or the session is rolled-back.
> ({{Session#rollback()}}).
> {{AMQSession.deregisterConsumer()}} contains the following code:
> {code}
> if (_transacted)
> {
> _removedConsumers.add(consumer);
> }
> {code}
> However, the {{_removedConsumers}} list is only cleaned up on rollback and
> nowhere else.
> This leak appears to be longstanding. It looks like it was added at M3
> (QPID-832).
