PrePersist is called on object although no merge/persist operation is cascaded/applied
--------------------------------------------------------------------------------------

                 Key: HHH-6958
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6958
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 4.0.0.Final, 4.0.0.CR2
         Environment: JBoss AS 7
            Reporter: Benjamin Diedrichsen
            Priority: Critical


The scenario: A persistent instance of class A is loaded. A transient object of type b is created and with it a transient object of type c. Then the merge operation is invoked on A.
The unexpected behaviour now is that the @PrePersist method on C is called although the causing merge-operation does not apply (not cascaded from B to C) and is actually not executed on the object (--> C will not be persisted to the database).

Why is PrePersist invoked for C if no persist or merge operation is actually cascaded?

Class A{
@OneToOne(cascade = CascadeType.ALL, optional = true, orphanRemoval = true)
private B b;

}

Class B{

@ManyToOne(optional = false, cascade={CascadeType.PERSIST})
	private C c;

}

Class C{
// some basic attributes here
}
