> Cattelan. Link to the thread
> :http://openjpa.208410.n2.nabble.com/N-query-problem-with-Version-td6027619.html
> The problem occurs if a null value is returned for an entity's version field.
> In this case OpenJPA will issue a second select statement to re-fetch the
> version, potentially resulting in a lot of repetitive SQL statements.
