Brent Courtois Thanks for reaching out.

Could you create a self contained test case outside of Spring Boot with our test case template: https://github.com/hibernate/hibernate-test-case-templates/tree/master/orm/hibernate-orm-5 ?

I suggest you to change the version of ORM to 5.2.17 in the pom as the issue might have been fixed in 5.3.x and that would prevent from reproducing the issue.

Thanks!
