Keith Wall updated QPID-6951:
-----------------------------
Description:
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).
