> Key: AMQ-3027
> URL: https://issues.apache.org/jira/browse/AMQ-3027
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.4.1
> Environment: Windows Server 2008 for broker, Windows 7 for clients,
> NMS
> Reporter: Mark Gellings
> Priority: Major
> Fix For: NEEDS_REVIEW

> I am using message groups with ActiveMQ 5.4.1 and when ending the group I'm
> seeing some odd behavior.
> I run two consumers on Queue A. There is a 200ms delay when processing a
> message. I have a producer send 500 messages with group A to the broker with
> the last having a group sequence of -1. The first consumer starts processing
> messages from group A while the producer is creating the messages, but as
> soon as the broker gets the message with group sequence of -1 that message
> gets sent to the second consumer, and then the remaining in the group go to
> the second consumer. So the processing is out of order and all the messages
> don't go to the same consumer.
> I believe only messages created after the one with group sequence of -1
> should go to the second consumer. And the message with -1 sequence gets
> processed last. Should this also be the case if the master broker fails
> over during this time?
> Issue AMQ-2952 does not appear to be the same issue. Unfortunately I do not
> have time to test this against the current snapshot or include a test case.
> The scenario, however, is very simple and I'm sure it would be easy to whip
> up an example.
