> As a leftover from event refactoring, the listeners in the StateChangeDispatcher are still
> managed by a WeakIdentityCollection and for every notify event, it's synchronized and copied
> into an array. this is very expensive and unnecessary.
> since the addition and removal of listeners is now controlled, and listeners can't just disappear,
> it possible to use a normal collection.
> Suggest to replace the WeakIdentityCollection by a
> 'EDU.oswego.cs.dl.util.concurrent.CopyOnWriteArrayList' that allows read access (and iteration)
> without synchronization.
