[JBoss-user] [Messaging, JMS & JBossMQ] - Re: different order between sending and receiving(FIFO)

[<ad...@jb...>]

Nope, just a *stupid* receiver class.

Because it only waits for 1 milli-second, you are see nacks back to the server
because you do a receive(1) request then stop waiting.
Which JBoss correct reports later as messages (1 and 2) being redelivered

  | message.getJMSRedelivered()
  | 

Once redelivery is involved, ordering is out of the window.

Change the test to wait for a reasonable amount of time
receive(100ms) // 0.1 seconds
and then you won't have this receive/stop waiting/nack race condition.
