制約事項

Static methods are ignored by validation. Putting constraints on a static method is not portable. No other restrictions exist from the perspective of this specification, however it is possible that technologies integrating with method validation impose further restrictions to methods for which a validation shall be applied. For instance certain integration technologies might require that methods to be validated must have public visibility and/or must not be final.

staticメソッドはJSR380としてNG、publicじゃないとダメなのはSpringか
