The classes referenced by the validatedBy *are* the validator classes
at least if by validator you mean ConstraintVaildator implementation
of the custom constraint, so they have to be in the classpath to be
mirrored by the AP machinery :)
For built-in types it's a bit different as the @Constraint is not
filled up and has to be simulated.
