> Key: HHH-3945
> URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3945
> Project: Hibernate Core
> Issue Type: Bug
> Components: envers
> Affects Versions: 3.5.0.Beta-1
> Environment: 3.2.6.ga
> Oracle 10g
> Reporter: robbie123456
> Assignee: Adam Warski

> Using Envers version 3.5.0-SNAPSHOT:
> class A extends from B. They both have @Entity and B has with @Inheritance(strategy=InheritanceType.JOINED), so fields in the subclass A have a separate table.
> When only setting A to @Audited, I get following NullPointerException (found closed JIRA ticket: https://jira.jboss.org/jira/browse/ENVERS-71):

> NullPointerException happens here because 'entitiesConfigurations' is empty:
> String parentEntityName = pc.getSuperclass().getEntityName();
> ExtendedPropertyMapper parentPropertyMapper = entitiesConfigurations.get(parentEntityName).getPropertyMapper();
> When also putting @Audited to the superclass B, I get following exception (also found on Hibernate JIRA ticket: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3647):
