I have a frame, which contains a choice & List. I have added KeyListener, itemListern to the choice. I am consuming the keyevent in keyPressed(). . I try to click on the choice & try to select the item using arrow key. The item event is generated when the items are selected using keyboard. Which is wrong .

import java.awt.Frame;
import java.awt.Choice;
import java.awt.List;
import java.awt.Robot;
import java.awt.event.InputEvent;
import java.awt.event.KeyEvent;

public class ConsumeEventAndCheckEventFire implements java.awt.event.ItemListener , java.awt.event.KeyListener , java.awt.event.ActionListener {
    private Frame frame=null;
    private Choice ch=null;
    private List lst=null;
    ConsumeEventAndCheckEventFire() {
        frame = new Frame("Test ConsumeEventAndCheckEventFire ");
        frame.setLayout(new java.awt.FlowLayout());
        ch = new Choice();
        ch.add("One");
        ch.add("Two");
        ch.add("Three");
        ch.add("Four");
        ch.add("Five");
        ch.add("Six");
        ch.add("Seven");
        ch.add("Eight");
        ch.add("Nine");
        ch.add("Ten");
        ch.addItemListener(this);
        ch.addKeyListener(this);
        lst = new List();
        lst.add("One");
        lst.add("Two");
        lst.add("Three");
        lst.add("Four");
        lst.add("Five");
        lst.add("Six");
        lst.add("Seven");
        lst.add("Eight");
        lst.add("Nine");
        lst.add("Ten");
        lst.addItemListener(this);
        lst.addKeyListener(this);
        lst.addActionListener(this);
        frame.add(ch);
        frame.add(lst);
        frame.pack();
        frame.setVisible(true);
    }
    public void itemStateChanged(java.awt.event.ItemEvent ie ) {
        System.out.println(ie);
    }
    public void keyPressed(java.awt.event.KeyEvent ke) {
       // System.out.println(ke);
        ke.consume();
    }
    public void keyReleased(java.awt.event.KeyEvent ke){
    }
    public void keyTyped(java.awt.event.KeyEvent ke){
    }

    public void actionPerformed(java.awt.event.ActionEvent ae) {
        System.out.println(ae);
    }
    public static void main(String []args) {
        new ConsumeEventAndCheckEventFire();
    }
}

This fails on solaris & pass on windows. I tested this on 1.4.2 to mustang b105 & even in jdk7.0 b10.
