[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-3708) Suboptimal exception on m:n relations with an unaudited entity

Suboptimal exception on m:n relations with an unaudited entity -------------------------------------------------------------- Key: HHH-3708 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3708 Project: Hibernate Core Issue Type: Improvement Components: envers Affects Versions: 3.3.1 Environment: Hibernate 3.3.1, Envers 3.4-Snapshot, Java 6, Spring 2.5 Reporter: Eike Hirsch Assignee: Adam Warski Priority: Minor Fix For: 3.5 The following code will produce a NullPointerException on listener startup when **B** is not audited. The exception should state that there is an audited collection to an unaudited entity. (And for debugging it would be really cool to log both entity class names) {code} @ManyToMany( cascade= {CascadeType.ALL} ) public List<B> getBs() { return bs; } {code} As described in http://www.jboss.com/index.html?module=bb&op=viewtopic&t=148392. {code} 2009-01-09 16:46:11.872::WARN: Nested in org.springframework.beans.factory.BeanCreationException: E rror creating bean with name
