The InputEvent.ALT_MASK modifier is not being properly applied to MouseEvent
objects in JRE 1.4.0_beta2. Below is an application that demonstrates that
when the ALT key is pressed and a click occurs, the ALT_MASK (value == 8) is
not added to the 'modifiers' member of the MouseEvent as it is with the
CTRL_MASK and SHIFT_MASK.


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

public class AltModifierTest extends JFrame
  {
//
// Main Method
//
  public static void main(String[] arg)
    {
    AltModifierTest alt = new AltModifierTest();
    alt.setSize(100, 100);
    alt.setLocation(200, 200);
    alt.setVisible(true);
    } // ends main(String[])

//
// Constructors

  public AltModifierTest()
    {
    this.addMouseListener(new MouseAdapter() {
      public void mousePressed(MouseEvent me)
        {
        System.err.println("press detected with modifiers " + me.getModifiers());
        System.err.println(" MouseEvent.SHIFT_MASK: " + MouseEvent.SHIFT_MASK);
        System.err.println(" MouseEvent.CTRL_MASK: " + MouseEvent.CTRL_MASK);
        System.err.println(" MouseEvent.META_MASK: " + MouseEvent.META_MASK);
        System.err.println(" MouseEvent.ALT_MASK: " + MouseEvent.ALT_MASK);
        } // ends mousePressed(MouseEvent)

      } // ends anonymous MouseAdapter class

    ); // ends addition of MouseListener

    } // ends constructor AltModifierTest(void)

  } // ends class AltModifierTest
