After swapping the right/left component on componentOrientation, if user reset/remove+add another to either left/right won't it cause confusion?
For example in this piece of code the frame ends up containing component one to right and another to left though I'm adding both the component to right. 

JSplitPane jsp = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT,
       null, new JButton("Right_First"));
jsp.setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);
jsp.setRightComponent(new JButton("Right_Second"));
JFrame frame = new JFrame();
frame.add(jsp);
frame.pack();
frame.setVisible(true);
