Java 11 issue with Bytebuddy/sun.misc.Unsafe

I am trying to use Hibernate Core 5.4.1 Final along with Bytebuddy 1.9.7 which both should be Java 11 compliant.

When instantiating the Session Factory I get the below error:

Thanks for your support!

Looks like a bug. Try to replicate it using this test case template and open a Jira issue afterward.
