I tried 5.2 RC3 and it seem to have new bugs. It dispatching duplicates. One of my test run resulted below:
Messages sent: 1000 (using 50 threads 20 times) Consumers: 2 trasacted Queue Attributes in JConsole: DequeCount: 1000 DipatchCount: 4849 EnqueueCount:1000 InFlightCount: 3849 QueueSize: 49 Consumer end: Received: 2025 Its acting weird. when I tried with Non-transacted+Auto Ack, it sent duplicates and also the broker was still holding on to all of 1000 messages. I will try to come up with a JUnit test case. But this is faily staright forward case when messages are sent faster than they can be consumed!!
