Answer 1

I had also the same problem. It was because of an incompatibility between Hibernate and Java. I see your Hibernate is 6.0.0.Final. If your Java is 1.8 or lower than that, then it will create a problem. For 6.0.0.Final Hibernate, you must have at least Java 11.

Here is the link: https://hibernate.org/orm/releases/

Answer 2

I had a similar problem. Hibernate is 6.1.5.Final worked for me.
