The finalize() method is not normally guarranteed to be called.  There
is a class method provided (under the System(?) class) called
runFinalizersOnExit() that will make sure all finalizers are called.

However, this method has been deprecated ( or was as of 1.2beta4 ).

My suggestion is to provide a close() method of some type in your
subclass of JInternalFrame & call that.  I would also use the
finalize() method to make sure that the close() method had been
called, and signal an error if it has not been.  This will have the
effect of having the finalize() method do a check on the use of the
object; which can effectively tell you if resources are getting closed
even if it's not always invoked.
