See the related discussion on beanvalidation-dev, the motivation for having a JPA-aware resolver by default is that one doesn't want to trigger loading of lazy references also during validation in the REST/service layer etc. Your best option is to use a custom resolver which always returns true and, once HV-1487 Pull Request Sent is released, you could disable the caching to get some further perf improvement.

I'm going to close this issue, as there's nothing we can do otherwise. Thanks!
