Ok. Here is a link to the JavaDoc how NetBeans handles this for PropertyChanges


I still do not understand the necessity for creating a new interface,
it contains no additional information (API) - for the user it can only
be used as an EventListener (assuming there will be no API explicitly
requiring WeakEventListener)..

>> I also considered to define the WeakEventHandler as an interface which extends EventHandler, but adds no additional methods. Then leave it to event handler containers to reference such event handlers weakly. This has very simple and direct usage, but also its own problems. We can discuss it further if you find this solution preferred to the wrapper approach.
