Tilmann Zäschke commented on JDO-751:
-------------------------------------
I think there still is a problem when writing {{postcode == null}} in a query.
If {{postcode}} is of type {{Optional}} and the {{Optional}} references
{{null}}, should the query match the object (because the Optional references
null) or not (because the reference to the optional is not null)? In Java this
is not ambiguous.
> Support for Java8 Optional

> 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"
