I've just done my project... River Data Report/Calculator Program...
I encountered this when closing the program...

Im using Frame...
@ CloseOperation, I've used dispose() and System.exit();

I'd tried to trap that exception... Like putting all methods with try/catch for debugging purposes.. but i can't....

My last Option is i did put a JOptionPane before the System.exit(0) in closingOperatio n method... and that stacktrace prints after i click the ok button in the JOptionPane... So for me that exception occured between System.exit(0) and the Garbage Collector... I didn't use finalize method...

Can you explain it to me Experts?!! I mean that Exception...
I really feel bad about that exception...

Have you encountered this Exception?
Can you share what you have learned about that Exception?


Any reply will be appreciated...

I'm guessing, but it looks like an attempt to use JFileChooser after Swing has shut down.

Thanks bro, i've implemented a method that would make the object equal to null before the dispose and exit calls... Your right, At my JFileChooser...

The exception now trapped...thank s for the reply...

Is it ok that i equate that object into null? Is there a disadvantage?

is the object consumes an amount of memory at RAM? or in general purpose registers in Processors?

That was just a guess on my part. I wouldn't worry about memory consumption. I would just try to make the shutdown code as clean as possible.
