If we want to include a type-safe approach later on, we might do it like
this:

* Pull ConstraintValidator#initialize() up into a new interface
Initializeable
* Change @CrossParameterConstraint#validatedBy() to return Class<?
extendsInitializable<?, ?>>. AFAICS that shouldn't be a problem for
existing
constraint definitions, BV providers need of course to adapt. Short tests I
did looked good.
