DragAndDrop java.lang.RuntimeException

Question

I am learning Drag and Drop, but for every single example that I want to study, I get the folowing exception java.lang.RuntimeException: cannot load system cursor: CopyDrop.32x32 . Does anyone know what is the meaning of this exception and how can I fix it? Even with this example I get that exception.

I have a minimal example ,I get same exception.

    public DragAndDrop() {
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setBounds(100, 100, 450, 300);
    contentPane = new JPanel();
    contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
    contentPane.setLayout(new BorderLayout(0, 0));
    setContentPane(contentPane);
    TransferHandler transfer = new TransferHandler("text");

    JPanel panel = new JPanel();
    contentPane.add(panel, BorderLayout.CENTER);

    JTextArea textArea = new JTextArea();
    textArea.setDragEnabled(true);
    textArea.setTransferHandler(transfer);
}
