This seems to contradict the spec of BasicOptionPaneUI#initialFocusComponent and the spec of the BasicOptionPaneUI#selectInitialValue() itself?


    /** Component to receive focus when messaged with selectInitialValue. */
    protected Component           initialFocusComponent;

    /**
     * If inputComponent is non-null, the focus is requested on that,
     * otherwise request focus on the default value
     */
    public void selectInitialValue(JOptionPane op) {
