When a validator is invoked in a standalone Java version via

ValidatorFactory validatorFactory = Validation.buildDefaultValidatorFactory();
Validator validator = validatorFactory.getValidator();
validator.validate(someclass, null);

the following warning is created three times at log output for each invocation of "validate"
WARN: HHH015016: Encountered a deprecated javax.persistence.spi.PersistenceProvider [org.hibernate.ejb.HibernatePersistence]; use [org.hibernate.jpa.HibernatePersistenceProvider] instead. – HibernatePersistence.logDeprecation()

Note: I don't know if this has any effect, but the Java programm also loads previously the Hibernate 4.3 ORM Mapper for other operations via PersistenceProvider provider = new HibernatePersistenceProvider();
EntityManagerFactory factory = provider.createEntityManagerFactory("ExporterPU", null);
