I think that Optional itself is treated as embedded. I’d investigate which
field is causing the problem by trying, one at a time, Optional<?>,
Optional<OptionalSample>, etc. and see whether any of these is ok.
But is Optional even claimed to be supported by datanucleus? I haven’t seen any
mail on the subject…
