What you're trying to do is apparently not possible:

You cannot show the PopupMenu with its show method since you need to specify a JComponent but your TrayIcon isn't one (weird enough though that TrayIcon still manages to do it, so apparently there is a way, don't ask me though..). So, as MadProgrammer suggested, you should try using JPopupMenu instead. Don't add it to your TrayIcon for that won't be possible, but display your JPopupMenu by adding a MouseListener to your TrayIcon. That should do the trick:

final TrayIcon tray = new TrayIcon( img, tooltip, null);
final JPopupMenu menu = new JPopupMenu();
... // your menu initialization.
tray.addMouseListener( new MouseAdapter() {
    @Override
    public void mouseClicked(MouseEvent evt) {
        menu.setLocation( evt.getPoint() );
        menu.setVisible( true );
    }
}
