Description

Here's the scenario:

B1 = Broker 1
B2 = Broker 2
R1 = Polling Message consumer connected to B1
R2 = Polling Message consumer connected to B2
S1 = Message producer connected to B1

B1 and B2 are started – they find each other and "hookup"
R1 and R2 are started – they connect and call receive() on Q
S1 is started – connects and sends 10 messages to Q.

R1 receives messages: 0,2,4,6,8
R2 receives messages: 1,3,5,7,9

Restart R1 (complete shutdown of JVM) — here's where the bug starts showing

R1 receives messages: 3,7
R2 receives messages: 1,5,9

Restart R2 (complete shutdown of JVM) — nothing happens (no
messages are redelivered)

Restart R1

R1 receives messages: 5
R2 receives messages: 1,9

Restart R1

R1 receives messages: 9
R2 receives messages: 1

Restart R1

R1 receives messages: <nothing>
R2 receives messages: 1

And if you keep restarting R1 the final loop happens over and over again.

I'll attach a sample with instructions on how to run it.
