Description
In merlin, cut/copy/drag are broken for JEditorPane when its EditorKit is an RTFEditorKit. Thus, setting the content-type to "text/rtf" or explicitly setting the EditorKit to an RTFEditorKit will prevent cut/copy/drag from working.

To see the problem, compile and run the following:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.text.*;

public class EditorPaneRTFTest extends JFrame {

    JEditorPane ep = new JEditorPane();

    public EditorPaneRTFTest() {
        setTitle("EditorPaneRTFTest");
        setSize(500, 400);

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
        setLocation((d.width - getWidth()) / 2, (d.height - getHeight()) / 2);
        
        ep.setContentType("text/rtf");
        try {
            ep.getDocument().insertString(0, "Try copying or moving this.", null);
        } catch (BadLocationException ble) {
        }
        ep.setDragEnabled(true);

        getContentPane().add(new JScrollPane(ep), BorderLayout.CENTER);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                EditorPaneRTFTest test = new EditorPaneRTFTest();
                test.setVisible(true);
            }
        });
    }

}

Try copying the text (CTRL-C) - nothing is copied to the clipboard.
Try cutting the text (CTRL-X) - nothing is put on the clipboard and no text is removed.
Try dragging and dropping the text - the drag and drop completes and no text is transferred.

The expected result is that plain text should be moved/copied around.

EVALUATION This problem occurs because the RTFEditorKit.write() method always throws an IOException. When the TextTransferable defined in BasicTextUI sees this exception, it clears itself to represent an empty transfer. ###@###.### 2001-10-11 BasicTextUI has been changed so that it always exports "text/plain" using getSelectedText(). "text/plain" will also now always be imported using insertString(). This means that even when RTF fails to be exported through write as "text/rtf", "text/plain" will still be offered. This is how it used to be before this regression. ###@###.### 2002-04-04
