>    Affects Versions: 3.2, incubation
>         Environment: Windows XP, JDK 1.5.0_11
>            Reporter: Piotr Bzdyl
>            Assignee: Guillaume Nodet

> Currently org.apache.servicemix.jms.AbstractJmsProcessor.start()  starts JMS connection (and thus starts fetching messages on all already registered and all new registered listeners) before org.apache.servicemix.jms.multiplexing.MultiplexingConsumerProcessor initializes its pendingMessages map in doStart() method.
> It can be resolved by:
> 1) moving initialization of MultiplexingConsumerProcessor.pendingMessages before consumer.setMessageListener(this); Also initializing MultiplexingConsumerProcessor.channel field should be done before any message arrives via listener's onMessage method.
> OR
> 2) starting JMS connection in org.apache.servicemix.jms.AbstractJmsProcessor.start() after whole initialization in subclasses is done (after doStart())
> I am attaching patch for the first solution.
