>> Test issue shows the End and Start buttons are not placed as per instructions due to ComponentOrientation RTL was not honoured, as with `getContentPane()` being removed from `add` call of JFrame, it was also additionally removed from other JFrame calls which resulted in the RTL not being propagated to its child. Fix is to add `getContentPane()` to the non-add methods of JFrame as was done in the applet version of the test..
