The problem encountered is a discrepency between the KeyEvent.getKeyCode()
return value for KeyPressed events. On one system, Linux Redhat7.1, pressing the
SHIFT and +/= button results in a VK_SHIFT followed by a VK_PLUS. This is what I
believe to be the correct behavior. On the second system, Windows 2000, the same
combination of keystrokes results in a VK_SHIFT followed by a VK_EQUALS.

Try this code to demonstrate :

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


public class KeyTest extends JTextField{

  public KeyTest() {
    setPreferredSize(new java.awt.Dimension(200,200));
    addKeyListener(new KeyAdapter() {
      public void keyPressed(KeyEvent e) {
        divulgeError(e);
      }
    });
    requestFocus();
  }

  public void divulgeError(KeyEvent e) {
    Class k = java.awt.event.KeyEvent.class;
    java.lang.reflect.Field[] f = k.getDeclaredFields();
    for (int i = 0; i < f.length; i++) {
      try {
      if (f[i].getName().indexOf("VK_") < 0) continue;
      if (f[i].getInt(null) == e.getKeyCode())
        System.out.println(f[i].getName());
      } catch (Exception ex) {ex.printStackTrace();}
    }
  }

  public static void main(String[] args) {
    KeyTest test = new KeyTest();
    JFrame frame = new JFrame();
    frame.getContentPane().add(test);
    frame.pack();
    frame.setVisible(true);
  }
}
