Tilmann Zäschke commented on JDO-751:
-------------------------------------
Interesting. I had tried it with variables, but they only gave me the basic <E>
or <T> type. It didn't expect that fields behave differently and give you the
actual generic type, but it appears they do.
Still, we can only catch it if the generic type is actually given and precise
enough (not {{<Object>}} or {{<?>}} or omitted).

> 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"
