> There is a logic bug in the handling of stopping the CaptureChangeMySQL 
> processor. This causes it to not stop while there are events in the queue. If 
> the processor isn't running fast enough to drain the queue, stopping the 
> processor will have no effect.
> The logic was being handled in OnStopped, but that won't get called until the 
> onTrigger has finished. Instead the loop should be checking to see if the 
> processor is still scheduled using isScheduled(), and if not should break out 
> of the loop and finish the onTrigger processing, thereby allowing the 
> OnStopped logic to be executed.
