If always-on-top frame has a child dialog, it loses its always-on-top property. The following simple test demonstrates the problem:

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

public class AlwaysOnTopTest
{
  public static void main(String[] args)
  {
    Frame g = new Frame("AOT Frame w/o child");
    g.setBounds(000, 000, 200, 100);
    g.setAlwaysOnTop(true);
    g.setVisible(true);

    Frame f = new Frame("AOT Frame");
    f.setBounds(100, 100, 200, 100);
    f.setAlwaysOnTop(true);
    f.setVisible(true);

    Dialog d1 = new Dialog(f, "Non-AOT modeless Dialog", false);
    d1.setBounds(200, 200, 200, 100);
    d1.setVisible(true);
  }
}

The only difference between frames f and g is that there is a child dialog d1 for frame f. This leads to f to be not always-on-top.
