Re: [hibernate-dev] Fail fast feature for Hibernate Validator

Too sad, that javax.validation.ValidatorContext is not defined as public interface ValidatorContext <V extends ValidatorContext<V>> { } If it were, we wouldn't need a dedicated method HibernateValidatorFactory#usingHibernateContext(), but HibernateValidatorFactory could be defined as public interface HibernateValidatorFactory extends ValidatorFactory { HibernateValidatorContext usingContext(); } then, allowing the validator to be retrieved like that: failFastValidator = factory.unwrap(HibernateValidatorFactory.class) .usingContext() .maxConstraintViolationCount(5) .getValidator(); Yes I've hesitated back in the days and thought unwrap was enough :( I wonder if we can retroactively enhance it without breaking clients.
