I think this is the issue report in Spring Data JPA: https://jira.spring.io/browse/DATAJPA-1280

As a workaround, you can downgrade to Spring Data release train Kay-SR4 (SR5 is the current latest version and is the version used in Spring Boot 2.0.0). Just add:

<spring-data-releasetrain.version>Kay-SR4</spring-data-releasetrain.version>

to your pom.xml's <properties> section.
