        Description

        Test background:
        ----------------
        I am running an application that opens up a Frame/Dialog/Window in which a volatile image is rendered. I am running this app on a multi-monitor (2 monitors) virtual screen WinXP configuration. This frame is initially created on one of the screens and then moved to another screen after it is made visible. Actually this test expects the volatile image to get invalidated and re-created (IMAGE_INCOMPATIBLE) when it is moved from one GD to the other.

        Behavior Seen:
        --------------
        Application is moved by calling setLocation() repeatedly with increasing or decreasing x,y value depending on the virtual config being horizontal or vertical. On Mustang-b51+, the frame stays in-between the two screens and it freezes. I don't see any IMAGE_INCOMPATIBLE being returned when the VImage is validated.

        This is noticed only on Mustang-b51 and I am not able to reproduce it on b50. This is seen only on WinXP (Platform Info is given under Comments section) and passes on Linux + Xinerama. Hence looks like this is a regression introduced in b51.

        I have attached a sample test and couple of other supporting files, images. Please run the test on the primary screen as follows:
        java MoveWindowVirtualScreenTest

        This will show an undecorated frame on the sec screen and will move it to the primary. Check the renderings are proper. If you see frame getting stuck in-between the 2 monitors, the bug is reproduced. Also check whether 'IMAGE_INCOMPATIBLE' message is shown on the console.
        (This test will loop through all the GCs for each GD, all the GDs, Window, Frame (decorated/undecorated) and Dialog top levels). This occurs intermittently. I reproduced it 7 times out of 10 trials. So run the app a few times if you don't see it the first time.
        Here is the thread dump at the time of hang:
