Put the focus in a JTextArea and press Alt+Right, this types a "B".
I tried to trace the origin of the problem and it seems to come from the type-ahead feature that generates a keyTyped event.
This is a major problem for JDeveloper since those keys are used to navigate between editors.

The following case is a trivial application that creates a JTextArea. Run the application and type Alt+Left, Alt+Right, Alt+PgUp, ... and you will see that characters are typed into the text.

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

public class Application1
{
  public static void main(String[] args)
  {
    JFrame frame = new JFrame();
    frame.getContentPane().setLayout(new BorderLayout());
    frame.getContentPane().add(new JTextArea());
    frame.setBounds(100, 100, 200, 200);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setVisible(true);
  }
}

The problem is reproducable with JDK1.4.0 and 1.4.1 but was not present in previous releases.

======================================================================
I can reproduce the bug on Win2k.
Do not see what it has to do with the text package.
Take a look at the following example.

--

import java.awt.*;
import java.awt.event.*;

public class Application1 {
    public static void main(String[] args) {
Frame frame = new Frame();
Panel panel = new Panel();
frame.add(panel);
panel.addKeyListener(
new KeyAdapter() {
public void keyPressed(KeyEvent e) {
System.out.println("Application1.keyPressed "+e);
}

public void keyTyped(KeyEvent e) {
System.out.println("Application1.keyTyped "+e);
}
public void keyReleased(KeyEvent e) {
System.out.println("Application1.keyReleased " + e + "\n");
}
}
        );
frame.setBounds(100, 100, 200, 200);
frame.setVisible(true);
    }
}

When Alt+Right is pressed
java.awt.event.KeyEvent[KEY_TYPED, keyCode=0, keyChar='B', keyLocation=KEY_LOCATION_UNKNOWN] get generated.

That is why 'B' is typed in JTextArea.
