Hi, A couple of days ago I've submitted a pull request for WFLY-471 which is about updating the WildFly Hibernate Validator module to HV 5.x as well as updating the RESTeasy validation integration module to match this version [1]. Could someone have a look at this PR and let me know whether it's ok? All tests pass and the test build was successful. Thanks, --Gunnar [1] https://github.com/wildfly/wildfly/pull/4693
