Tilmann Zäschke updated JDO-751:
--------------------------------

Sorry, I think overlooked your post.
You raised an excellent point about JDOQL that return {{false}} if one in
{{person.address.postcode}} is {{null}}.
So this would for example answer point e) (we disallow Optional<Optional<>>),
and c) (return {{false}}).
I think it leaves points a) metadata (Renato's point), and b)/d) about
comparison to {{null}}/{{empty}}. Disallowing comparison to {{null}} could have
quite some impact I suppose...
