I have frame with a button which invokes a dialog(modaless). when the dialog is visible , the dialog which has the button has the focus. I minimize the frame, the dialog also get minimized. When i click on the iconified frame on the taskbar or system tray. The frame & dialog visible ( normal state), Now i would expect that dialog button should have the focus, but the frame button is having the focus. This works fine in jdk1.4.2 , jdk1.5.0 , jdk 6.0 & it even works fine in jdk 7.0 till b03 , but fails from jdk7.0 b04 onwards. So this is a regression. It even works fine in 6u1. 

Step to reproduce:
------------------
1) Run the below program.
2) Click on the  "ShowDialogButton" button in the frame( which is having the focus)you will see a dialog.
3) Observe that dialog button is having the focus.
5) Minimize the frame. Both frame & dialog will be minimized.
5) Click on the frame (iconified) on the taskbar or systemtray.
6) Frame & Dialog is visible. Observe that Frame button is having the focus. Actually dialog button should have the focus. 

import java.awt.*;
public class TestFocus {
    private Frame frame=null;
    private Dialog dialog=null;
    private Button showDialogButton=null , dialogButton=null;
    TestFocus( ) {
        frame = new Frame();
        frame.setLayout(new java.awt.FlowLayout());
        showDialogButton = new Button("ShowDialogButton");
        showDialogButton.addActionListener(new java.awt.event.ActionListener(){
            public void actionPerformed(java.awt.event.ActionEvent ae){
                dialog = new Dialog(frame , "Test focus Owner",false);
                dialog.setLayout(new java.awt.FlowLayout());
                dialog.add(dialogButton = new Button("DialogButton"));
                dialog.pack();
                dialog.setLocation(200,200);
                dialog.setVisible(true);
            }
        });
        frame.add(showDialogButton);
        frame.pack();
        frame.setVisible(true);
    }
    public static void main(String []args){
        new TestFocus();
    }
}
