When a Choice is added to the CENTER of a a Frame with a BorderLayout, the Choice is placed in different locations on Solaris and Windows. On Windows, the Choice is located in the center of the Frame (more or less where you would expect); on Solaris, the Choice is placed in the upper-left corner of the Frame.

This bug is present in 1.2.2, 1.3 (or will be, as soon as the fix for 4323906 is integrated), and 1.4.

The following code pretty clearly demonstrated this:
/* Test to demonstrate the difference in positioning of Choices between
 * win32 and Solaris.
 */

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

public class DiffChoice extends Frame {
    Choice theChoice;

    public DiffChoice() {
        super("Different Choice Locations");
        theChoice = new Choice();
        theChoice.add("I'm just little black rain cloud");
        theChoice.add("Hovering under the honey tree");
        setLayout(new BorderLayout());
        add(theChoice, BorderLayout.CENTER);
    }

    public Dimension getPreferredSize() {
        return new Dimension(400,400);
    }

    public Dimension getMinimumSize() {return getPreferredSize();}
    public Dimension getMaximumSize() {return getPreferredSize();}

    public static void main(String[] args) {
        DiffChoice dc = new DiffChoice();
        dc.addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });
        dc.pack();
        dc.show();
    }
}

This bug is filed in response to the fix for The fix for 4255631 fixed this problem, but caused 4323906, so the code was removed for Kestrel.
