I struggled with this issue, too. I found out that the Hibernate community has RESOLVED the issue in Hibernate version 5.4.10, here is the ticket: https://hibernate.atlassian.net/browse/HHH-8091

You can check your Hibernate version System.out.println(org.hibernate.Version.getVersionString());

And you can UPDATE the version of Hibernate to the latest, here is a useful link: https://bintray.com/hibernate/artifacts/hibernate-orm#
