There is a class org.hibernate.type.decriptor.ValueExtractor which conflicts with javax.validation.valueextraction.ValueExtractor.
Either rename org.hibernate.type.decriptor.ValueExtractor or find a more specific name for javax.validation.valueextraction.ValueExtractor. After all ValueExtractor is probably a very overloaded class name.

BTW why isn't org.hibernate.type.decriptor.ValueExtractor an impl package?
