    20   * <p>{@link BeanUtilsBean} implementation that creates a
    21   * {@link ConvertUtilsBean2} and delegates conversion to
    22   * {@link ConvertUtilsBean#convert(Object, Class)}.
    23   * </p>
    24   *
    25   * <p>
    26   * To configure this implementation for the current context ClassLoader invoke
    27   * <code>BeanUtilsBean.setInstance(new BeanUtilsBean2());</code>
    28   * </p>
    29   *
    30   * <p>
    31   * BeanUtils 1.7.0 delegated all conversion to String to the converter
    32   * registered for the <code>String.class</code>. One of the improvements in
    33   * BeanUtils 1.8.0 was to upgrade the {@link Converter} implementations so
    34   * that they could handle conversion to String for their type (e.g.
    35   * IntegerConverter now handles conversion from an Integer to a String as
    36   * well as String to Integer).
    37   * </p>
    38   *
    39   * <p>
    40   * In order to take advantage of these improvements BeanUtils needs to change
    41   * how it gets the appropriate {@link Converter}. This functionality has been
    42   * implemented in the new {@link ConvertUtilsBean#lookup(Class, Class)} and
    43   * {@link ConvertUtilsBean#convert(Object, Class)} methods. However changing
    44   * {@link BeanUtilsBean} to use these methods could create compatibility
    45   * issues for existing users. In order to avoid that, this new
    46   * {@link BeanUtilsBean} implementation has been created (and the associated
    47   * {@link ConvertUtilsBean2}).
    48   * </p>
