> Duplicate messages dispatched when using AMQ Store

> Key: AMQ-1452
> URL: https://issues.apache.org/activemq/browse/AMQ-1452
> Project: ActiveMQ
> Issue Type: Bug
> Components: Message Store
> Affects Versions: 5.0.0
> Reporter: David Sitsky
> Assignee: Rob Davies
> Priority: Critical
> Fix For: 5.0.0

> Attachments: duplicate.log

> This issue was originally reported on activemq-user here:
> http://www.nabble.com/Duplicate-message-delivered-to-consumers-on-queue-with-kaha-persistence-tf4560327s2354.html.
> When I initially reported this issue, Rob suggested to not use Kaha
> persistence, but using the AMQ store. This seemed to resolve the issue.
> Unfortunately, I have seen another situation where a duplicate message is
> being re-delivered, it turns out to the same consumer. I have tried in vain
> to create a unit test to reproduce this, but have been unable to do so.
> The offending message ID is ID:tamarama-63606-1191905255404-2:2:3:3:1, and if
> you look at the attached debug trace, you can see it being sent to a queue,
> read from a queue, and then being dispatched a second time. The same worker
> thread in this case was the producer and the consumer of message.
> This issue does not occur when persistence is not enabled.
> This is seen with revision 583015.
