Spring Two beanvalidation test packages look the same

There are two test packages . one is 'org.springframework.validation.beanvalidation2' in spring-context-support, another is 'org.springframework.validation.beanvalidation' in spring-context. Is there a special purpose?

The only reason for it is that we test against distinct generations of the Bean Validation API - 1.1 and 2.0 - and corresponding Hibernate Validator versions there, and can only really separate those dependencies into different modules there.
