/**
* {@link BeanUtilsBean} implementation that creates a
* {@link ConvertUtilsBean2} and delegates conversion to
* {@link ConvertUtilsBean#convert(Object, Class)}.
*
*
*
* To configure this implementation for the current context ClassLoader invoke
* BeanUtilsBean.setInstance(new BeanUtilsBean2());
*
*
*
* BeanUtils 1.7.0 delegated all conversion to String to the converter
* registered for the String.class. One of the improvements in
* BeanUtils 1.8.0 was to upgrade the {@link Converter} implementations so
* that they could handle conversion to String for their type (e.g.
* IntegerConverter now handles conversion from an Integer to a String as
* well as String to Integer).
*
*
*
* In order to take advantage of these improvements BeanUtils needs to change
* how it gets the appropriate {@link Converter}. This functionality has been
* implemented in the new {@link ConvertUtilsBean#lookup(Class, Class)} and
* {@link ConvertUtilsBean#convert(Object, Class)} methods. However changing
* {@link BeanUtilsBean} to use these methods could create compatibility
* issues for existing users. In order to avoid that, this new
* {@link BeanUtilsBean} implementation has been created (and the associated
* {@link ConvertUtilsBean2}).
