Query the source of the event like jthis :

Object o = e.getSource();

if(o instanceof JOptionPane)
  return;
else { // the esc was generated on the main JDialog
  if ( e.getKeyCode() == KeyEvent.VK_ESCAPE)
    MyDialog.this.dispose();
}

I don't see the JOptionPane reference, but they are both using the same key listener can both have the same method.  Therefore, if the dialog is open it will respond any time to the escape key being pressed--irregardless if there is something else open.  Or even is something else is listenening to that key press event.  Just to play with it change the key that it is listening for to a different one.  That way you can have two dialogs open and not close both at the same time, or design a method a determine which dialog was active when the key was pressed.  There I would override the dispose method and do a quick check to see if it is active before disposing.
