[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2146) NullpointerException in DefaultDeleteEventListener.deleteTransientEntity

Andrew Timpone commented on HHH-2146:
-------------------------------------

Is there anyway to raise the priority on this issue?
We recently upgraded from Hibernate 3.0.x to 3.2.2 and are starting to see this error pop up in quite a few issues.
At surface level, this appears to be a relatively simple fix (not knowing the deep inner guts of Hibernate), but a null check before comparing to the transientEntities would easily solve the issue.

>          URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2146
>      Project: Hibernate3
>         Type: Bug

>     Versions: 3.2.0.cr5
>  Environment: Hibernate 3.2.0cr5, Oracle10g
>     Reporter: Martin Kartumovich
>     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.
