私は、最小限の例を持って、私は同じ例外を取得。
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);
}

これはJava Swingの質問ですか？あなたはあなたが試したことの最小限の例を入れてもらえますか？ –
Googleを検索するこれについて多くのバグレポートがあります。おそらくあなたのOSとJDKのバージョンは関連しているでしょう。 – Gendarme
