Subject Behavior when a message expires while it is processing
Date Fri, 11 Apr 2014 23:25:52 GMT
Hi,

I am trying to understand the behavior when a message expires while it is
being processed. I have the following flow setup in my test program.

queue.start -> sleepProcessor -> queue.end

The sleepProcessor takes the message from queue.start and sleeps for 5
seconds. I send a message to queue.start with a JMSExpiration of 1 second
from System.currentTimeMillis(). I have setup dead letter queues for each
queue named DLQ.queue.start and DLQ.queue.end.

The behavior I see is that 1 message ends up in DLQ.queue.start and another
message ends up in DLQ.queue.end.
How does 1 message become 2?

The test program can be found here with source
testJMSExpiration.zip
<http://activemq.2283324.n4.nabble.com/file/n4680241/testJMSExpiration.zip>  

I have included a maven pom.xml and the test program can be run with the
following command
mvn camel:run

OS: Linux 3.5.0 (Mint 14)
JVM: 1.6
ActiveMQ: 5.7.0
Camel: 2.8.2

Any insight would be greatly appreciated.
Thank you
