I would not expect nothing more of a "retort" after such an issue is ignored for 3 years if I were you.
But probably my point of view is wrong as I am just the ugly guy who is not going to contribute and is just going to try and use another jpa provider.

From my point of view opening an issue is already a form of contribution, and ignoring such contribution is ... well ... just wrong.

I have my own projects/frameworks/duties and fixing hibernate is not among them.

Covering your head with sand have lower probability in making Hibernate better than my retorts.
