JMenuBar is not appearing (just showing thin grey line)

Question

I'm using Eclipse on a Mac running Mavericks, but that shouldn't be the problem. I seem to be doing nothing wrong, I just can't get this JMenuBar to show up on my JFrame even after trying repaint() and revalidate(), here's the code and picture of the grey line that is showing up..

create the JFrame.. (this object is created in a Runnable(run()) in the driver)

public GUIPhotoAlbum ()
{
    super("PhotoAlbum");
    usersAlbum = new PhotoAlbum();

    setIcon();

    this.setSize(875, 625);
    this.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
    setLayout(new BorderLayout(5, 5));

    initComponents();
    initMenuBar();
    repaint();
    revalidate();

    initTopPanel();
    add(topPanel, BorderLayout.CENTER);

    initBottomPanel();
    add(bottomPanel, BorderLayout.SOUTH);

    addListeners();

    setLocationRelativeTo(null);
    setVisible(true);
}

initMenuBar():

   private void initMenuBar()
        {
            menuBar = new JMenuBar();
            fileMenu = new JMenu("File");
            editMenu = new JMenu("Edit");
            helpMenu = new JMenu("Help");

            openItem = new JMenuItem("Open");
            saveItem = new JMenuItem("Save");
            exitItem = new JMenuItem("Exit");
            addItem = new JMenuItem("Add");
            modifyItem = new JMenuItem("Modify");
            deleteItem = new JMenuItem("Delete");
            aboutItem = new JMenuItem("About ...");

            fileMenu.add(openItem);
            fileMenu.add(saveItem);
            fileMenu.add(exitItem);

            editMenu.add(addItem);
            editMenu.add(modifyItem);
            editMenu.add(deleteItem);

            helpMenu.add(aboutItem);

            //sets the menu bar for the JFrame
            this.setJMenuBar(menuBar);
        }

Here's my JFrame window so far: ..That tiny grey line just below the top bar of frame goes away if you take out this.setJMenuBar(menuBar) from code

You haven't add anything to the JMenuBar

menuBar = new JMenuBar();
fileMenu = new JMenu("File");
editMenu = new JMenu("Edit");
helpMenu = new JMenu("Help");

menuBar.add(fileMenu);
menuBar.add(editMenu);
menuBar.add(helpMenu);
