Hot reload/compile doesn't fit well with bean validation

See discussion on #137 : when first POJO validation occurs, hibernate validator caches annotations metadata on the POJO class instance (see here)

If we change the POJO structure, and add/remove some validation constraints on it, hot reload/compile is triggered but these changes are not reflected during bean validation since cached annotation metadata are taken into consideration.

My bad, seems like the issue was a false positive, hot reload works well.
Seems like the cached metadata belongs to the Validator (thus, instantiating a new Validator on each request would prevent from reusing previous constraints metadata)
