Christopher Hunt commented on CAMEL-1064:
-----------------------------------------

Thanks for this. Was this a 1.6.0 fix for Camel? You implied that the ActiveMQ 
Camel component was changed also; or is it because of 5.2.0's connection 
factory change that Camel's component inherits the fix?

>             Project: Apache Camel
>          Issue Type: Bug
>          Components: camel-activemq
>    Affects Versions: 1.4.0, 1.5.0
>         Environment: Mac OS X (10.5), Java 1.5, ActiveMQ 5.1.0
>            Reporter: Christopher Hunt

> If the ActiveMQ broker is shut down and then started again while a Camel 
> ActiveMQ endpoint based program is listening on its queue, the program does 
> not pick the queue back up for consuming when ActiveMQ is back up. Anything 
> subsequently posted to the new broker becomes available only when the Camel 
> program is restarted.
> This is a problem in production style scenarios where the broker has to be 
> restarted for some reason e.g. so that modifications to its configuration can 
> be made.
> I have been able to observe the above behaviour with the 
> camel-example-jms-file project and attach a modified version of the 
> CamelJmsToFileExample.java file. My modifications bind to the broker at 
> tcp://localhost:61616 and cause the example to pause for 20s before sending 
> out any messages. In this time, if the broker (which has to be started 
> externally prior to executing the example) is shutdown and then started 
> again, no messages are received.
> Here are the actual recommended steps to reproduce the problem:
> 1. Start the ActiveMQ broker in one terminal window
> 2. Run the example via mvn compile exec:java
> 3. When the message displays stating that you have 20s, Ctrl-C the broker in 
> the broker terminal window
> 4. When the broker stops, start it again
> At this point no messages are displayed - you would expect them to be - they 
> have actually been sent out. This can be verified also:
> 5. Type mvn compile exec:java again
> 6. Let the example continue without interfering with the broker.
> You will now see the messages posted previously prior while the program waits 
> for 20 seconds (remember no messages have been posted at this point). Letting 
> the example continue demonstrates that after the 20 seconds, the messages are 
> sent out and then received quickly given that we have not touched the broker.
