This is a known-bug observed on spring-boot 1.4 versions, wasn't seen on 1.3.x versions as it was silently swallowed.

As a workaround, you can switch-off spring-boot auto-configuration of Hibernate by adding the below changes.

1. Add @EnableAutoConfiguration(exclude = HibernateJpaAutoConfiguration.class) to you application class
2. spring.data.jpa.repositories.enabled=false to your application.properties/yml file

Hope this helps and good luck!
