----------------------------------
> Converters can return an invalid result object if a default value is set

> Key: BEANUTILS-445
> URL: https://issues.apache.org/jira/browse/BEANUTILS-445
> Project: Commons BeanUtils
> Issue Type: Bug
> Components: ConvertUtils & Converters
> Affects Versions: 1.8.3
> Reporter: Oliver Heger
> Fix For: 1.9.0
>
>
> For BeanUtils converters derived from {{AbstractConverter}} it is possible to
> set a default value. If the default flag is set, this value is returned for
> *null* input, but also if a conversion to an unsupported type is attempted
> (in this case, a conversion of the default value to the target class is
> tried, but if this fails, the default value is returned directly). This
> causes the converter to return an object of another class than requested.
> IMHO this is a source of ClassCastExceptions and should be changed. A
> converter should never return an object of a different type than the
> requested target class. So either perform a successful conversion (if
> necessary, convert the default value to the target class) or throw an
> exception.
