NPE on Cascade after switch to hibernate 3.5
--------------------------------------------

                 Key: HHH-5267
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5267
             Project: Hibernate Core
          Issue Type: Bug
          Components: annotations, core
         Environment: Hibernate 3.5.x
            Reporter: Krzysztof Kowalczyk
            Priority: Blocker


We use hibernate annotations and hibernate search in our project. After we moved to hibernate 3.5.2 (and 3.5.1 before that) we are having the following errors:

java.lang.NullPointerException

The NPE is thrown because "loadedState" field is null. The exception seems to occur for instance when we have OneToOne with Cascade.DELETE_ORPHAN (or orphanRemoval="true"), CascadeType.SAVE_UPDATE and CascadeType.DELETE.

I will try to create a simple example to reproduce the problem.
