The problem is that this is just *your
Well, Paul, your own last response was about the framework and about
Java. I sure am getting quizzical about these interjections.
I cannot raise these questions simply in relation to WeakReference,
etc. They are an ongoing issue about one look at the Struts framework

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

Thank

E.g.
package com.crackwillow.deploy;
import java.lang.ref.WeakReference;
import java.lang.ref.Reference;
public class MyReference {
public static void main(String [] params) {
Stringstring = new String("Aa");
Created a string containing "Aaa".

Stringstring = new String("Aaaaaa");
WeakReference wr = new WeakReference(string);
wr = replace(wr);

A WeakReference is just a way of holding a reference to an object that
will not keep it from being garbage collected (a very useful thing).
There are also ways that you can track when it has been garbage
collected. Once it has been garbage collected, it's gone though. All
you have i
Working here on a "new" paradigm, sort of, I think.
Apparently you can track what has happened to a strong reference with
a weak reference but you cannot manipulate the object referred to by
the strong reference by manipulating the weak reference. Is that
right? Seems odd to me.
