| * QPID-293 Setting MessageListener after connection has started can cause messages to be "lost" on a internal delivery |
| * queue <p/> The message delivery process: Mina puts a message on _queue in AMQSession and the dispatcher thread |
| * take()s from here and dispatches to the _consumers. If the _consumer1 doesn't have a message listener set at |
| * connection start then messages are stored on _synchronousQueue (which needs to be > 1 to pass JMS TCK as multiple |
| * consumers on a session can run in any order and a synchronous put/poll will block the dispatcher). <p/> When setting |
| * the message listener later the _synchronousQueue is just poll()'ed and the first message delivered the remaining |
| * messages will be left on the queue and lost, subsequent messages on the session will arrive first. |
