> (this report applies to BeanUtils 1.6.1)
> When using BeanUtils.copyProperties, if the source and destination beans have
> properties of the same name but with different types, the system throws a
> java.lang.IllegalArgumentException. This is NOT recorded as a thrown
> exception
> in the BeanUtils.copyProperties API. I think that this only happens if a
> Converter is not registered for the object.
> I personally think throwing an exception is a bug and that copyProperties
> should just fail silently (i.e. - don't populate that property of the
> destination bean). However, if an exception is deemed most appropriate by
> the
> committers, I think it should be added to the contract of the method. If a
> committer could weigh-in on this issue and decide which behavior is most
> appropriate, I can submit the needed patch.
