I have a list. I am pressing arrow keys and see ISC triggered by the list. Then i am clicking on the last item of the list. Then pressing 'clear' button.
This code is executed:
        list.removeAll();
list.requestFocusInWindow();
After that, if i am pressing 'UP' arrow key, the ISC will be triggered by the list regardless of the fact that the list is empty.

This is reproducible only on XToolkit.
This is reproducible with jdk6.0b38.

Here's the test case:

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

public class ListTest extends Frame implements ItemListener, ActionListener {

List list = new List();
Button b = new Button("clear");

public ListTest () {
super ("ChoiceTest");
list.add("111");
list.add("222");
list.add("333");
list.add("444");

list.addItemListener(this);
b.addActionListener(this);

add(list);
add(b);
this.setLayout(new FlowLayout());

setSize(200, 200);
setVisible(true);
validate();

}

public void actionPerformed (ActionEvent ae) {
list.removeAll();
list.requestFocusInWindow();
}

public void itemStateChanged (ItemEvent ie) {
System.out.println(ie);
}

public static void main (String args[]) {
ListTest test = new ListTest();
}
}
