Wie bewegen Sie die Form in Java?

Ich Formen zeichnen auf JPanel in einem separaten thread. Ich möchte zu bewegen, diese Formen durch Aufruf der Methode move() aber die Figur nicht ändern seine Lage.

Diese meine CustomShape

public class CustomShape {
    private static final int Y_STEP = 5;
    private static final int X_STEP = 5;
    public String name;
    public Shape shape;
    public Color color;
    private Point newLocation;

    public void move() {
        newLocation.x += X_STEP;
        newLocation.y += Y_STEP;
        //How set new location ?
        //It doesn't work
        this.shape.getBounds().setLocation(newLocation);        
        System.out.println(String.format("New location is [%d,%d]",newLocation.x, newLocation.y));
        System.out.println(String.format("Move to [%d,%d]", this.shape.getBounds().getLocation().x, this.shape.getBounds().getLocation().y));       
    }

    public CustomShape(Shape shape, Color color, String name) {
        this.shape = shape;
        this.color = color;
        this.name = name;
        newLocation = this.shape.getBounds().getLocation();
    }

Beispiel für die Ausgabe auf der Konsole

New location is [15,15]
Move to [10,10]
New location is [20,20]
Move to [10,10]
New location is [25,25]
Move to [10,10]

Mein JPanel

public class ViewPanel extends JPanel {
    private static final long serialVersionUID = 5252479726227082794L;
    private List<CustomShape> shapeList = new ArrayList<CustomShape>();
    private Map<String, Thread> threads = new HashMap<String, Thread>();
    private Timer timer;
    private static final int TIMER_SPEED = 1000;

    public ViewPanel() {
        super();
        this.setDoubleBuffered(true);
        timer = new Timer(TIMER_SPEED, null);

        timer.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                testMove();
            }
        });
    }
    private void testMove() {
        for (CustomShape shape : shapeList) {
            shape.move();
        }
    }

    public void startMove() {
        timer.start();
    }

    public void stopMove() {
        timer.stop();
    }

    public void addShape(CustomShape shape) {
        shapeList.add(shape);
        if (!threads.containsKey(shape.getName())) {
            Thread t = new Thread(new DrawThread(shape, this.getGraphics()),
                    shape.getName());
            threads.put(shape.getName(), t);
            t.start();
        }
        this.repaint();
    }

    public void removeShape(CustomShape shape) {
        if (threads.containsKey(shape.getName())) {
            Thread t = threads.remove(shape.getName());
            t.interrupt();
            shapeList.remove(shape);
        }
        this.repaint();
    }
}

Thread für das zeichnen von Formen

public class DrawThread implements Runnable {
    private static final int THREAD_SLEEP = 100;
    private CustomShape shape;
    private Graphics2D g2d;
    private boolean interrupted = false;

    public DrawThread(CustomShape shape, Graphics g) {
        this.shape = shape;
        this.g2d = (Graphics2D)g;
    }

    @Override
    public void run() {
        while (true) {
            try {
                Thread.sleep(THREAD_SLEEP);
                g2d.setColor(this.shape.getColor());
                g2d.draw(this.shape.getShape());
            } catch (InterruptedException e) {
                System.out.println(String.format("interrupt %s", Thread
                        .currentThread().getName()));
                interrupted = true;
            } finally {
                if (interrupted)
                    break;
                }
        }
    }
}
