    031     * BeanUtils 1.7.0 delegated all conversion to String to the converter
    032     * registered for the <code>String.class</code>. One of the improvements in
    033     * BeanUtils 1.8.0 was to upgrade the {@link Converter} implementations so
    034     * that they could handle conversion to String for their type (e.g.
    035     * IntegerConverter now handles conversion from an Integer to a String as
    036     * well as String to Integer).
    037     * </p>
    038     *
    039     * <p>
    040     * In order to take advantage of these improvements BeanUtils needs to change
    041     * how it gets the appropriate {@link Converter}. This functionality has been
    042     * implemented in the new {@link ConvertUtilsBean#lookup(Class, Class)} and
    043     * {@link ConvertUtilsBean#convert(Object, Class)} methods. However changing
    044     * {@link BeanUtilsBean} to use these methods could create compatibility
    045     * issues for existing users. In order to avoid that, this new
    046     * {@link BeanUtilsBean} implementation has been created (and the associated
    047     * {@link ConvertUtilsBean2}).
    048     * </p>
