The fix is not available in any release yet. You can get this fix only by checking out code from svn.

The fix will be in 3.2.7 and 3.3.2 when they are released.

>             Project: Hibernate Core
>          Issue Type: Bug

>         Environment: Hibernate 3.2.0cr5, Oracle10g

>            Assignee: Gail Badner
>            Priority: Minor

> The following setup leads to a NPE in DefaultDeleteEventListener.deleteTransientEntity:
> Tables A, B
> Table V_A_B that is an M-N-Connection between A and B.
> Pojo for A has a Set of V_A_Bs.
> Pojo for B has a Set of V_A_Bs.
> Pojo C that has Sets of As and Bs.
> Cascades: all, delete-orphan
> -Create a new A and add a new V_A_B to its Set, that references to an existing B.
> -Delete B.
> -SaveOrUpdate Pojo C.
> In Hibernate 3.1.3 this works fine.
> In 3.2.0cr4+cr5 the removal of B results into an cascading removal of the never persisted V_A_B in the Set of B instead of ignoring it.
> This leads to an incorrect state where deleteTransientEntity is called with transientEnties=null.
> When now calling transientEnties.contains(...) the NPE is thrown.
