Patrick Moore commented on HHH-2128:
------------------------------------

... I should add I spent a hours tying to figure out why my data was completely corrupted. It was not obvious that the problem was related to the database order of the data! 

Concider it a testiment to Hibernate -- that I spent a large amount time assuming that I had some programming bug :-)

> Please notice that this situation arose from the most minimal definition. Using the 'defaults' is what caused this issue!
> See attached zip for definitions and reproduction test case.
> Steps:
> 1. define two classes (Primary, Secondary) that have a one-to-one relationship.
> 2. save a primary with no assigned secondary object.
> 3. save another primary with a secondary object.
> 4. retrieve the first primary and it will have the secondary object saved in step 3.
> 5. retrieve the second primary and it will have no secondary object.
> Suggested solution:
> require that 'one-to-one' enforce an implicit non-null requirement between primary and secondary.
