Thank you for your help! Sorry, I did have many more printouts to stdout, but stripped them to make it easier to read.... It is interesting that you said the System.exit should should down everything, now I am stumped...but here are my responses:

I am sure shutdown is being called, because I can see that the GUI does shutdown/closes.

I do not believe the worker thread is stopping because AFTER I click on the shutdown button, I then see the GUI shutdown/close, BUT I still see the netbeans JMV stdout window say the jvm is running still, AND I can perform ONE LAST scan, AND THEN I see the netbean jvm window close, and the scanner beam is then silent.
