Component JSplitPane does not redraw its panel correctly after SetDividerSize(int) invocation.
Frame window of the following test contains a JSplitPane component with text area at the top and
buttons area in the bottom. First time divider size is set to 40 pixels.
If you click on button "10", method JSplitPane.SetDividerSize(10) will be invoked.
If you click on button "40", method JSplitPane.SetDividerSize(40) will be invoked.
After clicking on "10" you can see that left and right sides of divider is shown
incorrectly. Then if you resize frame window or click on divider, panel redraws correctly.
