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/preference/PreferenceManager.java
/**
     * Creates a new preference manager with the given
     * the path separator.
     *
     * @param separatorChar the separator character
     */
    public PreferenceManager(char separatorChar) {
        separator = new String(new char[] { separatorChar });
    }
    /**
     * Adds the given preference node as a subnode of the
     * node at the given path.
     *
     * @param path the path
     * @param node the node to add
     * @return <code>true</code> if the add was successful,
     *  and <code>false</code> if there is no contribution at
     *  the given path
     */
    public boolean addTo(String path, IPreferenceNode node) {
        IPreferenceNode target = find(path);
        if (target == null) {
			return false;
		}
        target.add(node);
        return true;
    }
    /**
     * Adds the given preference node as a subnode of the
     * root.
