Unhandled event loop exception with Hibernate Tools in Eclipse Oxygen - eclipse

Question

I'm getting an "Unhandled event loop exception" with Hibernate Tools in Eclipse Oxygen. I get this when I try to "Finish" the Hibernate Configuration Wizard below. Note, I've tried numerous combinations of the entries on this page & all lead to that exception.
1) How do I resolve this?
2) Are the Hibernate Tools worth the effort of resolving this?
It seems like these tools could be cool, if they worked.

Answer 1

I had the same problem. If I changed the Hibernate Version value to 5.1, I could "Finish" the wizard.

Answer 2

along with #halfpad solution if your still facing the issue update your java version.
