With xmls removed it works nicely(I hope I’m not overlooking anything), both in MWE and in our app. This is great, thanks for this workaround and lot of time/typing invested into me 🙂 I tried to debug HibernateValidator code myself, but it was very deep for first sight with no prior knowledge of code. regarding 3) yes it’s not ideal, but considering there is programmatic approach which can replace the xml, maybe the xml isn’t that needed whatsoever. But for older projects or projects which cannot be sure what BeanValidation provider they get, maybe. I don’t know. Thanks again for you support, I hope my mwe/report will was at leas ta little beneficial and will help you/someone as you helped me.
