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 which I have called HaD. If that is not tangentially okay on this list, then I think some people are just wound way too tight and I am in total disagreement with this approach. Some common sense would be advised, in my opinion.
