Not sure, that’s why I cross posted the link on that topic too with a link to this one:
I think it may actually be the validator not understanding the semantics of MySQL > 5.5 or not using the dialect or something along those lines. I think the hibernate tools mapping and the annotation is actually correct.
In any case, one of the two sides is not in agreement with the other for some reason.
I can’t believe I am the only person trying to get this to work, so I am guessing I am missing something very obvious such as something that appears to be new like hibernate.dialect.storage_engine = innodb and deprecation of the xxxInnoDB dialects but I am not entirely sure.
