[classlib][awt] Swing components lose focus immediately after gaining it by mouse press
---------------------------------------------------------------------------------------

                 Key: HARMONY-1547
                 URL: http://issues.apache.org/jira/browse/HARMONY-1547
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
         Environment: Windows XP/x86
            Reporter: Dmitry A. Durnev


All swing components which request focus on mouse click, such as buttons, radio buttons, comboboxes,
etc. get 3 focus events: FOCUS_GAINED, FOCUS_LOST, FOCUS_GAINED on each mouse press. This
leads to incorrect behavior of some components, for example in the following test
run on Harmony:

import javax.swing.ButtonGroup;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JRadioButton;


public class JButtonTest {
    public static void main(String[] args) {
        JRadioButton jb = new JRadioButton("button");
        JRadioButton jb1 = new JRadioButton("button1");
        ButtonGroup bg = new ButtonGroup();
        bg.add(jb);
        bg.add(jb1);
        JPanel p = new JPanel();
        p.add(jb1);
        p.add(jb);
        JFrame jf = new JFrame("radio button test");
        jf.getContentPane().add(p);        
        jf.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
        jf.pack();
        jf.show();        

    }

}

radio buttons only get focus on first mouse click, but don't get selected/deselected.
They have to be clicked twice to get selected.
