class	OptionalValidatorFactoryBean LocalValidatorFactoryBean subclass that simply turns Validator calls into no-ops in case of no Bean Validation provider being available.
class	SpringValidatorAdapter Adapter that takes a JSR-303 javax.validator.Validator and exposes it as a Spring Validator while also exposing the original JSR-303 Validator interface itself.
