I wrote a MDI application in Java. My main JFrame contains a menu and a
JDesktopPane. When a user selects a menu item, a corresponding
JInternalFrame is created and added to the JDesktopPane. After the user
closes the frame, I make sure dispose() is called on the frame... But this
does nothing! It keeps the reference and the memory, and when the user
selects the same menu-item again, memory grows. I noticed that - even though
I called dispose - the next time to JInternalFrame is created and shows, it
has the same values (like size and selections) as last time. Howcome? Even
when I wait for some time, the JInternalFrame is not carbage collected, but
when I try to reference it without calling new() I get a null-pointer
exception (and that is the only thing I can agree with!).

Is there some way to force or speeden garbage collection? And... why, if I
call dispose on a JInternalFrame, it is'nt disposed at all?

If things like these happen a lot, I would rather program I C++ - sure
you'll end up with memory-leaks, but at least you can conrol it (I hope I'm
wrong though).

Can someone help me out please? I've got a very dissapointed customer...
