[bv-dev] Invoking Configuration#buildValidatorFactory() several times

Hi all, based on a question in the HV user forum [1] I'm wondering whether it's legal to invoke buildValidatorFactory() several times on the same instance of javax.validation.Configuration: Configuration<?> configuration = Validation.byDefaultProvider().configure(); //set up interpolator, traversable resolver etc. configuration. ...(); ValidatorFactory vf1 = configuration.buildValidatorFactory(); //further customize configuration for another factory configuration. ...(); ValidatorFactory vf2 = configuration.buildValidatorFactory(); I'm not sure how often one would do something like this in practice, but I think we should make clear whether this is a valid use case or whether a Configuration instance is to be thrown away after invoking buildValidatorFactory(). After having a look at the spec and the API documentation I think it's currently unspecified. Any thoughts? Thanks, --Gunnar [1] https://forum.hibernate.org/viewtopic.php?f=9&t=1014788
