      Description

      When we load Java2Demo, than first comes a Frame with progress bar
      which show demo is loading images, etc
      Once this loading is complete same JFrame object is used by changing
      its size and adding demo panels over it. This reuse process needs to
      be handeld properly so that user don't feel it.
      Right now once progressbar is completely loaded, its moves little
      bit up and for a while java 2 demo's main window shows progress bar
      which gives bad impression of flicker.
      Attached Images clarify how user actually see this.
      Screenshot-1.png: It shows movement of Frame towards top while progressbar
                        is visible
      Screenshot-2.png: It shows movement java 2 main window with some tabs and
                        also progress bar of last window over them

      Steps to reproduce:
      1) Open Java 2 Demo
      2) Analyze properly the behaviour of application after loading is finished
         and before java 2 main windows shows up.

      Note: More clear to get this effect see properly in slower systems,
            it exist on all platforms.
