Due to changes in
CAMEL-11346, many processors (including SendProcessor) no longer send ExchangeSentEvent when processing is done. The StopWatch object is not created when EventHelper.notifyExchangeSending returns false. If no EventNotifier is registered to receive that event, it will be false. But an EventNotifier may still be registered to receive ExchangeSentEvent. The StopWatch should be created when there is an EventNotifier registered for ExchangeSentEvent even when ExchangeSendingEvent is not, unless those events are always required to be paired together.
