style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">The
            problem was that in the case of SCROLLBARS_NEVER, scroll bar
            info was set using setScrollInfo() with SIF_RANGE with
            ranges being (0, 0). This forced the windows to pick a
            default value and hence reset it to that value every time.
            Now the logic is modified in a very similar fashion as the
            other scroll bar display modes but without displaying it
            using the new win api ShowScrollBar(). The scroll bar info
            is supplied with a proper range per the corresponding base
            component but without the scroll bar pane size(as we don’t
            display it). This should suffice a good range for the scroll
            bars to operate and correct itself if there is any out of
            range value is supplied.<o:p></o:p></span></p>

style="font-family:"Calibri",sans-serif">The only difference
                          of SCROLLBARS_NEVER from others I got from
                          javadoc is that the scroll bar controls are
                          hidden. So the scrolling itself happens in the
                          same way as in the case of visible scroll bars
                          but it can be only controlled by mouse wheel
                          or programmatically. In my understanding this
                          means that the notification about the scrolled
                          component size changes should happen in the
                          same way as for all other cases. I see no
                          reason for the differentiation that your fix
                          introduces. What will happen if to remove this
                          notification for visible scroll bars modes?<br>
