/**
 * Idempotent EjbTimerServiceImplementation. Used if a Bean does not implement a timeout method or no auto-started timer is configured by annotation or deployment plan.
 * This differs from OpenEJB 2.x behavior, which did not create a TimerService for a bean which did not have a timeout method.
 * There's nothing in the spec which says a timeout-less bean cannot call getTimerService. So, we now have NullEjbTimerServiceImpl, which does not do very much...
