Description copied from class: ServiceSupport

Implementations override this method to support customized start/stop.

This method will also be invoked if the service is still in uninitialized state (eg has not been started). The method is always called to allow the service to do custom logic when the service is being stopped, such as when CamelContext is shutting down.

Exception
