I write small hibernate application and get following stacktrace:
org.hibernate.cfg.beanvalidation.IntegrationException: Error activating Bean Validation int
Just remove the javax.validation dependency
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>1.0.0.GA</version>
</dependency>
That fixed this particular problem on my end.
Hibernate Validator 5x is not compatible with validation-api 1.0.x
JPA 2.0 : Exception to use javax.validation.* package in JPA 2.0
