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
/**
     * Pre-order traversal means visit the root first,
     * then the children.
     */
    public static final int PRE_ORDER = 0;
    /**
     * Post-order means visit the children, and then the root.
     */
    public static final int POST_ORDER = 1;
    /**
     * The root node.
     * Note that the root node is a special internal node
     * that is used to collect together all the nodes that
     * have no parent; it is not given out to clients.
     */
    PreferenceNode root = new PreferenceNode("");
    /**
     * The path separator character.
     */
    String separator;
    /**
     * Creates a new preference manager.
     */
    public PreferenceManager() {
        this('.');
    }
