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

NullpointerException in DefaultDeleteEventListener.deleteTransientEntity ------------------------------------------------------------------------ Key: HHH-2146 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2146 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.2.0.cr5 Environment: Hibernate 3.2.0cr5, Oracle10g Reporter: Martin Kartumovich Assignee: Gail Badner Priority: Minor Fix For: 3.2.x, 3.3.x, 3.4 Attachments: Cascade.java, deletetransientmn.zip 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.
