      if (!display.readAndDispatch())
        display.sleep();
    }
    image.dispose();
    display.dispose();
  }
}

and the exception:

I copied your code, compiled and executed it without problems on a WinXP system with java 1.6.0-10

This looks like incompatibility between libraries, Java and Windows versions. Make sure you get versions of the products that match versions.
