Bug 161848 [JFace] Javadoc quality in org.eclipse.jface
As Tod announced on the platform-ui mailing list he wants to set the compiler settings to stricter mode so to ensure the javadoc quality. Because the weather was so lousy in Austria today I tried it and took the effort (~2 hours). I'll attach the patches package wise. This is a starting point.
bundles/org.eclipse.jface/src/org/eclipse/jface/action/SubMenuManager.java
IMenuManager {
    /**
     * Maps each submenu in the manager to a wrapper.  The wrapper is used to
     * monitor additions and removals.  If the visibility of the manager is modified
     * the visibility of the submenus is also modified.
     */
    private Map mapMenuToWrapper;
