> Looks like there is a race condition when handling multiple CASes coming in
> at the same time from the same client. The first thread creates a Connection
> and sets up a Session then the second thread sees the Connection made and
> proceeds to send a reply. The Connection has not yet started though,
> resulting in
> 20 Jan 2014 14:32:18,426 WARN DUCC.ActiveMQSessionExecutor - Received a
> message on a connection which is not yet started. Have you forgotten to call
> Connection.start()? Connection: ActiveMQConnection
> Start the Connection as soon as it is created in a synchronized block.
