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/SubToolBarManager.java
IToolBarManager {
    /**
     * Constructs a new manager.
     *
     * @param mgr the parent manager.  All contributions made to the 
     *      <code>SubToolBarManager</code> are forwarded and appear in the
     *      parent manager.
     */
    public SubToolBarManager(IToolBarManager mgr) {
        super(mgr);
    }
    /**
     * Returns the parent toolbar manager that this sub-manager contributes to.
     */
    protected final IToolBarManager getParentToolBarManager() {
        
        
        return (IToolBarManager) getParent();
    }
    /* (non-Javadoc)
     * Method declared on IToolBarManager.
     */
    public void update(boolean force) {
        
        
        
        getParentToolBarManager().update(force);
    }
}
