org.apache.cxf.ws.eventing.backend.notification.NotificatorService
The service which takes care of notifying subscribers about events. Has access to the subscription database. Receives events from compliant Emitters, eg. EmitterServlet / EmitterMBean,.. Don't forget to use the 'stop' method, especially if running inside a servlet container!! Suggested approach for a web container is to instantiate this class in a ServletContextListener and then have it stopped using the same listener. If you don't call 'stop' upon undeployment, the underlying ExecutorService will not be shut down, leaking resources.
