-------------------------------
I've attached a test case that implements the recreate steps described above.

> Key: AMQ-1710
> URL: https://issues.apache.org/activemq/browse/AMQ-1710
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker, Transport
> Affects Versions: 4.1.2
> Environment: Tested on 4.1.1 and 4.1.2
> Reporter: Rob Bugh
> Attachments: FailoverTest.java
>
>
> Recreate steps:
> 1) Start two brokers in JDBC Master/Slave topology
> 2) Create an app that puts two or more messages in a queue (two messages are sufficient). Give each message a JMXGroupID to force them to go to the same consumer.
> 3) Create another app that creates two connection to the broker and on each connection creates a session and a consumer with a unique clientID. Each should attempt to consume messages from the queue defined above.
> 4) Run the app and when the first message is consumed stop the master. Failover will occur and the slave becomes the new master.
> 5) Notice that when the transport resumes in the client that received the first message an exception like the following is thrown:
> javax.jms.JMSException: Transaction 'TX:ID:HOSTNAME-3289-1210016021661-0:1:1' has not been started.
> 6) Notice that the second consumer now recieves both messages.
