The java.awt.Frame.setMenuBar() method moves frame up on the screen after
the third call.

Set menubar twice (pressing the button) and the frame will move upward.

Here is the test demonstrating the bug:

-----------------MenuBarTest.java------------------------
import java.awt.*;
import java.awt.event.*;

class MenuBarTest extends Frame {
   int count = 1;
   MenuBar mb = null;

   MenuBarTest() {
        setLayout(new FlowLayout());
Button b = new Button("Add new MenuBar");
b.addActionListener(new choiceButton());
add(b);
createMenuBar();
   }

   void createMenuBar() {
        if(mb!=null) remove(mb);
mb = new MenuBar();
Menu m = new Menu("TestMenu"+count);
m.add(new MenuItem("one "+count));
m.add(new MenuItem("two "+count));
count++;
mb.add(m);
setMenuBar(mb);
   }

   public static void main(String argv[]) {
       MenuBarTest f = new MenuBarTest();
       f.setSize(300, 300);
       f.setVisible(true);
   }

   class choiceButton implements ActionListener {
     public void actionPerformed(ActionEvent e) {
String name = e.getActionCommand();
if(name.equals("Add new MenuBar")) createMenuBar();
     }
   }
}
