Thanks for the input. I am a little confused about your comment: 'The fact that you did not see the log from finalize() does not mean it did not happen.'
Are you saying that the finalize can be called and yet I may not get the log? How is that possible? I added the call to super.finalize() as you suggested (it didn't change anything), but please note that I really don't care about the finalize being called, except as a debugging tool. What I really want is a way to find out whether an object has been freed (or will be freed) or not. I believe that I must have objects that are not being freed, and I would like to try and identify them.
