That is, an overridden `installDefaults` may call its super while the overridden `uninstallDefaults` does not call its super (or vise versa). These classes are: `AquaTabbedPaneUI`, `SynthMenuItemUI`, `SynthSplitPaneUI`, and `XTextAreaPeer`.

Also I didn't see the need to include the @see changes in other methods in the CSR. They are not spec-relevant and clutter it
