Subject Re: [OT] Re: WeakReference

There are almost 800 people subscribed to this list. The first use of
the word "Struts" in this thread (now over a dozen messages) was in my
message, asking you to move the thread. I don't believe that's what
all those people expect to be reading about here.

If you want to develop your HaD ideas, then great! But have the Struts
part of the discussion here, and please ask your Java language
questions elsewhere. By your logic, this list would be open to any and
all Java language questions, and I for one am very strongly against
allowing that to happen.
