Craig, I am thinking of doing a wrapper, e.g. PointComposite, which will then not have to be updated, because it will only adapt the signatures of the interface Point (not implement Point) but that the actual object doing the work will be a PointImpl which will soley be a weak reference and available only and updated internally as a Point object through the PointHotFactory static methods. This would mean that there would be no strong reference to a Point class external to the PointComposite objects. Does this make sense to you? The class of the internal Point object, i.e. inside the PointComposite would be updated via a callback with a weak referenced listener. This may all be way too complex. If so, then I can abandon it, but I think it deserves a look. I think maybe it could be made simple.
