ServiceSupportServiceSupport.doStop() method when
the service is being stopped. This method will also be invoked
if the service is still in uninitialized state (eg has not

to do custom logic when the service is being stopped, such as when
CamelContext is shutting down.doStop in class EventDrivenPollingConsumerExceptionServiceSupport.doStart()protected void doShutdown() throws Exception
