The method MenuItem.enableEvents(long eventsToEnable) does not allow
subclasses of MenuItem to have the specified event types delivered
to processEvent method regardless of whether a listener is registered.

==== Here is the test demonstrating the bug ====
import java.awt.*;
import java.awt.event.*;

public class TestMenuItem extends MenuItem{

    public TestMenuItem (String label) {
super (label);
    }

    boolean processed = false;

    public void processEvent(AWTEvent e) {
processed = true;
    }

    public static void main (String args[]) {
String item = "Item";
TestMenuItem mi = new TestMenuItem(item);

/* part 1: enable action event */
mi.enableEvents(AWTEvent.ACTION_EVENT_MASK);
Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(
new ActionEvent(mi, ActionEvent.ACTION_PERFORMED, "Event"));
try { Thread.sleep(10000); } catch (Exception e) {
e.printStackTrace();
}
if (mi.processed) {
System.out.println("OKAY: processEvent invoked");
} else {
System.out.println("FAILED: processEvent not invoked");
}

/* part 2: add and remove listener;
action event enabled */
MyActionListener myal = new MyActionListener();
mi.addActionListener(myal);
mi.removeActionListener(myal);
Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(
new ActionEvent(mi, ActionEvent.ACTION_PERFORMED, "Event"));
try { Thread.sleep(10000); } catch (Exception e) {
e.printStackTrace();
}
if (mi.processed) {
System.out.println("OKAY: processEvent invoked");
} else {
System.out.println("FAILED: processEvent not invoked");
}
System.exit(0);
    }
}

class MyActionListener implements ActionListener {
  public void actionPerformed(ActionEvent e){}
}


==== Here is the output of the test ====
%java -fullversion
java full version "JDK-1.2fcs-P"
%java TestMenuItem
FAILED: processEvent not invoked
OKAY: processEvent invoked

 Justification:
The method should work properly
