Now, I’m getting closer to what I have in my code: the rank column is declared as int and not Integer, and in sql, as

  rank          int             not null default 0, 

With this, I do have a value in the JPA test, and the ORM test fails

Strangely in this test, I see the wrong value of rank used now: 1 instead of 0, but no null value in the list.
