Paul and Craig
I am getting what I expect with the following code (see below), thanks
to Craig, but not with the code which you can find at
http://131.191.32.112:8080/classes.zip and I am not sure what the
difference is. Essentially, I am trying to keep a WeakReference to
Point classes so that when I update the Point.class I can change the
classes for all the PointImpl objects out there. Not sure what is
going wrong. If you could take a peek, that would be great. Thanks.
Jack
