        <html><body><p>
        This test checks that when setState(Frame.ICONIFIED) is called before
        setVisible(true) the Frame is shown in the proper iconified state.
        The problem was that it did not honor the initial iconic state, but
        instead was shown in the NORMAL state.
        </p><hr/>
        Steps to try to reproduce this problem:
        <p>
        Select the different options for the Frame:
            <ul>
                <li><i>{Normal, Non-resizable}</i></li>
                <li><i>{Normal, Resizable}</i></li>
                <li><i>{Iconified, Resizable}</i></li>
                <li><i>{Iconified, Non-resizable}</i></li>
            </ul>
        After choosing the Frame's state click the
        Create Frame button.<br>
        After the Frame (Frame State Test (Window2)) comes up make sure the
        proper behavior occurred (Frame shown in proper state).<br>
        Click the Dispose button to close the Frame.<br>
        </p><hr/><p>

        Do the above steps for all the different Frame state combinations
        available.<br>
        For "Hide, Iconify and Show" case, the frame is hidden then iconified
        hence Window2 is not seen on-screen when shown as the frame is still
        in the ICONIFIED state. Window2 is visible on-screen when it is restored
        to NORMAL state as observed with "Hide, Iconify, Show and Restore" case.
        <br><br>

        If you observe the proper behavior for all the combinations,
        press PASS else FAIL.<br>
        </p><p>
        Note: In Frame State Test (Window2) you can also chose the different
        buttons to see different Frame behavior.<br>An example of a problem that
        has been seen, with the Frame non-resizable you can not iconify the Frame.
