[bv-dev] BVAL-341 - @Nullable

Hello, Matthew argues for a new basic constraint named `@Nullable`. The goal is to make it clear when an element is nullable. Today you can guess it from the fact that it does not host a `@NotNull` constraint. But it's ambiguous as someone might have simply forgotten the constraint. https://hibernate.onjira.com/browse/BVAL-341 I am not in favor of this for a few reasons. I think what Matthew is after is `@Nullable` with the semantic of JSR 305: the element is always nullable no matter what - and possibly can be computed by a tool at compile time. But since Bean Validation is only validated at specific moments in the life cycle of an object or method and that different groups can be validated, I don't feel that `@Nullable` would bring all the promises one would expect. Thoughts? Emmanuel
