> The current behavior (before this proposed change) is kind of complicated when an entity has a non-nullable, transient reference that is not resolved by cascading.
> When CHECK_NULLABILITY is true:
> - persist/save/merge event listeners will throw PropertyValueException;
> When CHECK_NULLABILITY is false:
> - if the entity insert action is executed before the session is flushed (i.e., an "early" insert to generate an identity ID), then JDBCException is thrown;
> - otherwise, TransientObjectException is thrown when the owning entity is dirty-checked.
> The proposed change would make the behavior consistent for all of these cases. If there are any "unresolved" non-nullable, transient entities after the top-level persist/save/merge event executes, then TransientPropertyValueException would be thrown, regardless of the CHECK_NULLABILITY setting.
> TransientPropertyValueException will extend TransientObjectException and will have the transient entity name and property path available (like PropertyValueException). Since it extends TransientObjectException, it will be remapped properly by Entity Manager.
