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.

public GridLayoutFactory spacing(int hSpacing, int vSpacing) {
        l.horizontalSpacing = hSpacing;
        l.verticalSpacing = vSpacing;
        return this;
    }
    /**
     * Sets the spacing for layouts created with this factory. The spacing
     * is the distance between cells within the layout. 
     * 
     * @param spacing space between controls in the layout (pixels)
     * @return this
     * @see #margins

    public GridLayoutFactory spacing(Point spacing) {
        l.horizontalSpacing = spacing.x;
        l.verticalSpacing = spacing.y;
        return this;
    }

    public GridLayoutFactory margins(Point margins) {
        l.marginWidth = margins.x;
        l.marginHeight = margins.y;
        return this;
