        Description

        OS: Windows XP SP3
        Java: JRE6u16

        swing components like JButtont, JScrollBar occasionally won't be repainted by mouse/key event.
        And the component image is sometimes painted to wrong position that is not on component's window.

        This issue was originally reported by the customer who run their own webstart application.
        But the issue was able to be replicated on my lab system with our sample webstart application.

        Then, repeart Step 2) - 6).
        Frequency of reproduction is very rare. It might need thousands of trials.

        Even the issue happen, the situation can be restored if you iconify and deiconify the window.
