This probably seems like a stupid question but what does a reference to a frame actually mean? JFrame frame1 = new CustomFrame1();
JFrame frame2 = new CustomFrame2( frame1 );
Now you have created frame2 by passing a reference ot frame1 to frame2. So now any code in frame2 has access to trame1, which means you could use the setVisible( false ) method on frame1, from an ActionListener in frame2. Its a terrible design as I don't see why the second frame would close the first frame, but it is possible.
