Any idea why we have WTKListenerList

[Roger Whitcomb]

Hi all,

    I'm looking at WTKListenerList.java and it says it was implemented 
to add thread-safety to the ListenerList abstract class.  But, AFAICT it 
does no such thing; it's simply an alias for ListenerList<T>.  Is this 
something that just never got implemented (the "thread safety" aspect)?  
Or is thread safety not needed in these cases?  Or ....?

    Trying to simplify code, for 2.1, so I'm thinking about getting rid 
of it, unless I need to worry about thread safety not being in here....

Thanks,
~Roger
