Or is this to say that *only* during graph validation a constraint may be validated multiple times but not e.g. during validation of multiple groups, all of which a constraint is part of? If you are just validating a single bean every constraint can only be validated once. However, when you are dealing with object graphs a constraint can be validated once per path on which you reach it. So both sentences make sense in their context, but taken together there seems to be a contradiction. Maybe the first statement could just be removed?
