Throw PropertyValueException if there are unresolved entity insert actions after persist/save/merge listeners execute
---------------------------------------------------------------------------------------------------------------------

                 Key: HHH-6957
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6957
             Project: Hibernate Core
          Issue Type: Improvement
          Components: core
            Reporter: Gail Badner
            Assignee: Gail Badner
             Fix For: 4.1.0


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 TransientObjectException would be thrown, regardless of the CHECK_NULLABILITY setting.
