    try {
        SystemTray tray = SystemTray.getSystemTray();
        ImageIcon icon=new ImageIcon(getClass().getResource("/images/Reg Member MO.png"));
        Image image = icon.getImage();
        TrayIcon icn = new TrayIcon(image, "This is demonstration system tray");
        icn.setToolTip("Now you can see system tray\ntooltip here\nThis is demonstration system tray ToolTip");
        tray.add(icn);     
        icn.displayMessage("This is demonstration System Tray message", "You can add some text to\ndisplay here as System Tray Message", TrayIcon.MessageType.INFO);
    } catch (AWTException ex) {
        Logger.getLogger(StartupSystemTray.class.getName()).log(Level.SEVERE, null, ex);
    }
}

May be your icon image is too large than allocated space. Try using public void setImageAutoSize(boolean autosize) method as icn.setImageAutoSize(true) . This will re-size the image.
