I have Frame which is having a button. I am clicking on the button so that a file dialog is visible. I am minimizing the frame & filedialog using start + "D" button on windows keyboard. Then i press ALT + Tab to see the window list & select the "Java cup" icon . I see the file dialog is restored. I am pressing "Escape" key so that file dialog get disappear. Now i see the frame is minimized on both on the taskbar (which is correct) & above that taskbar ( above the start button ). I have attached the screen shot of the same.

Run the attached program. click on the button a file dialog is visible. Press "Start + "D" button. you can see Press ALT + TAB key & select the java icon. File dialog is visible press "Escape" key. Observe that frame is seen above the taskbar. If you see the same then the bug is reproduced.

This works fine in jdk7 b13. but it is seen only in the pit build. This must be regression of http://monaco.sfbay/detail.jsf?cr=6503472. This is reproduced on windows platform only.
