Subject Re: NPE on JmsConsumer shutdown
Date Wed, 16 Feb 2011 09:30:41 GMT
Hi

The code in trunk has been improved when stopping/shutting down a
service as it will detect tis state pre action and only initiate the
operation if necessary.
That is only applicable if the service carries a state, such as
extending ServiceSupport (which most components does).

And I have just commited a fix in camel-jms to avoid that NPE.
