If you create a Scrollbar by just using the following constructor:

   new Scrollbar(Scrollbar.VERTICAL)

or

   new Scrollbar(Scrollbar.HORIZONTAL)

And you then try to click on the scrollbar's elevator, you will get the
following warnings:

    Warning:
    Name: scrollbar
    Class: XmScrollBar
    The scrollbar minimum value is greater than or equal to
    the scrollbar maximum value.

    Warning:
    Name: scrollbar
    Class: XmScrollBar
    The specified slider size is less than 1

This can be easily seen when running the JCK test: ComponentTest against
1.1 and clicking on the internal scrollbars.
