Tilmann Zäschke commented on JDO-751:
-------------------------------------

{{Optional.get}} will never give you back a {{null}}, it raises an
{{NoSuchElementException}}
{quote}
Ah, I hadn't realized that, that explains some things.
{quote}
Once using Optional everything that is non-Optional is automatically assumed to
be non-nullable. You need to pick one approach and delimit this world well.

I'm with you here, my concern was only that people are free to use {{null}}
outside {{Optional}}, and I think we need to make sure that we cover this (i.e.
think about it, not necessarily allow it), because it's perfectly valid Java,
even if it is not obviously sensible or what they 'should' do.
