Subject [jira] Created: (AMQ-1596) In 5.1-SNAPSHOTs, duplicate messages sent after broker restart

In 5.1-SNAPSHOTs, duplicate messages sent after broker restart

                 Key: AMQ-1596
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.1.0
         Environment: Windows and Linux
            Reporter: Richard Yarger

I am seeing duplicate messages delivered after bouncing the broker.
I have seen it happen in 5.1 SNAPSHOTS on 2/12 and 2/19.
It does not occur in 5.0.0.

I have persisted to both AMQ Store and to SQL Server.
It occurs for both.

Simple test flow:
1) Start the broker.
2) Start the consumer (running in Spring DefaultMessageListenerContainer)
3) Run the producer, which sends 5 new messages.
4) Messages are consumed.
Both the admin web app and jconsole show the messages as dequeued and a queue size of 0.
5) Bounce the broker.
6) The messages are resent to the consumer.

Spring's DefaultMessageListenerContainer is supposed to automatically acknowledge and commit
the session transaction, 
but I have tried manual acks and commits as well.
I am still able to reproduce.

I have broken down my code to the simplest test case that can reproduce the issue.
I am including this code and my broker config file.

Have I configured something incorrectly or is there an issue in 5.1?
Thank you.
