JMenu mmm = new JMenu("mmm");
JMenuItem b = new JMenuItem("b");
JMenuItem c = new JMenuItem("c");
JMenuItem d = new JMenuItem("d");

Not able to reproduce your problem. This is what I have tried:

    JFrame frame = new JFrame();
    frame.setSize(300,300);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    JPanel panel = new JPanel();
    JPopupMenu aaa = new JPopupMenu();
    JMenu mmm = new JMenu("mmm");
    JMenuItem b = new JMenuItem("b");
    JMenuItem c = new JMenuItem("c");
    JMenuItem d = new JMenuItem("d");
    JMenuItem k = new JMenuItem("k");
    mmm.add(b);
    mmm.add(c);
    mmm.add(d);
    mmm.add(k);
    aaa.add(mmm);
    panel.setComponentPopupMenu(aaa);
    frame.add(panel);
    frame.setVisible(true);

Nothing gets disappears. Is this the same you are doing?
