019/**
020 * <p>{@link BeanUtilsBean} implementation that creates a
021 * {@link ConvertUtilsBean2} and delegates conversion to
022 * {@link ConvertUtilsBean#convert(Object, Class)}.
023 * </p>
024 *
025 * <p>
026 * To configure this implementation for the current context ClassLoader invoke
027 * <code>BeanUtilsBean.setInstance(new BeanUtilsBean2());</code>
028 * </p>
029 *
030 * <p>
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>
