> I've tracked down the problem to a "@Column(nullable=false)". Specifically, if one of the objects in the result-set contain a null field that is defined as "nullable=false" then the above exception will occur.
> This behavior should either be documented in the Javadoc or the implementation should be changed to throw one of the declared exceptions instead. Also, the actual error message is misleading in that the specified object *is* found, but it violates the constraints of the ORM mapping.
