SwingUtilities - invokeLater usage

Question

I have a problem regarding invokeLater method - I am not sure if I understand correctly where I use should it. Take a look at the following code:

  public class Jumper implements Runnable {
    private Panel panel;
    private boolean running; 

    public Jumper() {
        LevelConfiguration levelConfiguration = new LevelConfiguration();// loads level configuration from the file
        Character character = new Character(levelConfiguration);
        Board board = new Board(levelConfiguration);

        Frame frame = new Frame();                                       // creates application's window
        panel = new Panel(levelConfiguration, character, board);         // creates panel and draw board and character
        frame.addComponent(panel.getPanel(), BorderLayout.SOUTH);
        InformationPanel infoText = new InformationPanel();              // creates JTextField...
        frame.addComponent(infoText.getTextField(), BorderLayout.NORTH); // ... and sets it above JPanel
        frame.packFrame();                                               // pack and set visibility

        start();
    }

    @Override
    public void run() {
        // do stuff and call render() method once in a while
        render();
   }

   private void render(){
        panel.getPanel().repaint();
    }

    private void start() {
        if (running) {
            return;
        }
        running = true;
        new Thread(this, "JumperMain-Thread").start();
    }
}

And Panel class:

 public class Panel {
    private JPanel panel;

    public Panel(final LevelConfiguration levelConfiguration, final Character character, final Board board) {
        int gamePanelWidth = levelConfiguration.getGamePanelWidth();
        int gamePanelHeight = levelConfiguration.getGamePanelHeight();

        panel = new JPanel(true)
        {
            @Override
            public void paintComponent(Graphics g) {
                super.paintComponent(g);
                board.drawBoard(g);
                character.drawCharacter(g);
            }
        };
        panel.setLayout(new FlowLayout());
        panel.setPreferredSize(new Dimension(gamePanelWidth, gamePanelHeight));
        panel.setBorder(BorderFactory.createEmptyBorder());
    }

I think that the proper way of using invokeLater in this code would be

1. from line Frame frame = … to frame.packFrame();
2. render() since it calls repaint()
3. last 3 lines in Panel class

Can someone confirm whether I think right or wrong?
