-----------------------------------

MemberMetadata.getFieldType should return "Optional<Address>". I don't see the
problem with type erasure, since the metamodel uses strings to represent types.

It would certainly work, but this would be inconsistent with containers i.e.
collections/maps/arrays, which are also parameterized types just like
Optional<T>, thus creating a special case just to support Optional. In my
opinion this would be not justifiable when you could just use the existing
approach for containers.

> java.util.Optional provides a feature that is available in other languages.
> Since JDO 3.2 will be for Java8+ then it makes sense to add support for this
> as a "supported persistable type"
