Martin Serrano updated AMQ-3380:
--------------------------------
Attachment: master-slave-exclusive-consumer-test.patch
Patch which adds a unit test that demonstrates this behavior. The test sends
100 messages. After 25 messages are sent, the master is stopped. The new
consumer gets 75 messages.
> Exclusive consumers do not rollback session when switched after master slave
> failover

> Reporter: Martin Serrano

>
> This is a pure master/slave setup with multiple transacted exclusive
> consumers. When the master is stopped, the exclusive consumer is switched
> (which seems odd to me). This would be okay except the prior consumer is not
> rolled back. The new consumer does not see all the messages (presumably
> since the prior consumer was not rolled back). In rare cases in my
> environment, I have experienced message loss -- a message does not get sent
> on the new consumer.
