As can be seen from DisplayMode source equals( DisplayMode ) doesn't check null.

    public boolean equals(DisplayMode dm) {
        return (getHeight() == dm.getHeight()
            && getWidth() == dm.getWidth()
            && getBitDepth() == dm.getBitDepth()
            && getRefreshRate() == dm.getRefreshRate());
    }

Also, shouldn't DisplayMode override equals( Object ) and call equals( displayMode ) if obj instanceof DisplayMode?
