[EventDispatcher] -besser nachvollziehbarer letzter beispielcode

[peterS.]

ein letztes "hallo" in die runde fuer alle Geduldigen und Interessierten,

[spam]: der zuletzt gepostete beispiel-code kommt hier nochmal
mit *debug*-ausgabe, um das grundlegende zusammenspiel der
komponenten besser nachvollziehbar zu machen ...

... bitte mit *copy and paste* auf die [jconsole] loslassen:
