956: Mainline

You can borrow nearly all you need for a popup menu from what you need for a menu bar. In particular, you can retain the fileMenuGeneral and fileMenuHorror menu items.

Now, however, instead of creating a subclass of the JMenu class, you create a subclass of the JPopupMenu class. You no longer need a JMenu instance variable; the JMenuItem instances connect directly to the MoviePopupMenu instance.

     MovieAuxiliaries.readMovieFile("horror.movies") 
    );
