      Java HotSpot(TM) Client VM (build 1.3.0beta-b04, mixed mode)

      /**
       * Synopsis:
       * When a menu is opened and the mouse is moved over the items on the menu,
       * they do not highlight under JDK 1.3 beta for Linux. But it works fine
       * with JDK 1.3 for Windows.
       *
       * Here is what java -version prints in the Linux version:
       * java version "1.3.0beta"
       * Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0beta-b07)
       * Java HotSpot(TM) Client VM (build 1.3.0beta-b04, mixed mode)
       *
       * Here is what java -version prints in the Windows version:
       * java version "1.3.0"
       * Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
       * Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode)
       *
       * Description:
       * Start the programm under JDK 1.3 for Windows and open the menu from the
       * menubar. Move the mouse (without pressing any buttons) over the menu and
       * notice how each menu item automatically highlights when the mouse moves
       * over it.
       * Now do the same thing under JDK 1.3 for Linux. The menu item do not
       * highlight here. The actions that are associated with the menu items are
       * triggered correctly, but the highlighting does not occur until an item is
       * clicked.
       *
