Verhindert die Methode MousePressed, dass MouseReleased in JLabel Drag & Drop ausgelöst wird?

<code class="java">Thumbnails[I_Loop].addMouseListener( new MouseAdapter() {
    public void  mouseReleased(MouseEvent me) {
           System.out.println("here mouse released");
      }
    public void mousePressed(MouseEvent me) {
        System.out.println("here mouse pressed");
        JComponent comp = (JComponent) me.getSource();
        TransferHandler handler = comp.getTransferHandler();
        handler.exportAsDrag(comp, me, TransferHandler.COPY);
    });</code>

<code class="java">// ...
private Point mousePt;
private Point dragPt;
private Rectangle bounds;

public MouseDragTest() {
    this.addMouseMotionListener(new MouseMotionAdapter() {

        @Override
        public void mouseDragged(MouseEvent e) {
            int dx = e.getX() - mousePt.x;
            int dy = e.getY() - mousePt.y;
            dragPt.setLocation(dragPt.x + dx, dragPt.y + dy);
            super.mouseDragged(e);
        }
    });
    this.addMouseListener(new MouseAdapter() {

        @Override
        public void mousePressed(MouseEvent e) {
            bounds = getBounds();
            Point p = SwingUtilities.convertPoint(this, e.getPoint(), Bounds.Parent);
            if (bounds.contains(p)) {
                dragPt = p;
