[bv-dev] BVAL-238 Dependency injection in ConstraintViolation

In your approach, the object cannot use constructor injection, correct?
What does Spring Framework do in this case, raise an exception?

It's not quite a wiki but that's pretty close. One thing you cannot do is create a new file unfortunately. Anyone that have asked for write access should see this button.
