I did run into this problem with JInternalFrames.  It seemed
that internalFrameClosed was called twice if the frame I was
closing was not in focus.  I couldn't figure out why it was
happening so I hacked it with a boolean "has_closed", in
the internalFrameClosed method:

(Initially has_closed = false.)

      if( !has_closed)
        {
        //Do your closed stuff.
       has_closed = true;
        }
