Thank you for taking care of the problem so quickly. I will check in a timely manner if their fix helps.

You are right, the comparison with integer literal or string literal is not good. In the case of integer literals, a high source of error, but also useful in some cases. I look forward to upcoming changes like the ones you mentioned in your comment, if they are coming.

In this case, it was the different behavior of Hibernate related to enum and enum as generic types that confused me.
