| Simple implementation of the ApplicationEventMulticaster interface.
Multicasts all events to all registered listeners, leaving it up to
the listeners to ignore events that they are not interested in.
Listeners will usually perform corresponding instanceof
checks on the passed-in event object.
By default, all listeners are invoked in the calling thread.
This allows the danger of a rogue listener blocking the entire application,
but adds minimal overhead. Specify an alternative TaskExecutor to have
listeners executed in different threads, for example from a thread pool.
