[hibernate-issues] [Hibernate-JIRA] Assigned: (HHH-4063) NPE reading metadata from an mapped interface

NPE reading metadata from an mapped interface --------------------------------------------- Key: HHH-4063 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4063 Project: Hibernate Core Issue Type: Bug Components: envers Affects Versions: 3.3.2 Environment: Hibernate-core 3.3.2GA, Envers 1.2.1GA Reporter: Hernán Chanfreau Assignee: Adam Warski Attachments: interface.mapping.test.zip, interfaceMappingSupportPatch.txt The problem arises when there is a mapped interface to load as a persistent class. The metadata reader from envers do not care about interfaces. See the discussion about it here: http://www.jboss.org/index.html?module=bb&op=viewtopic&t=156233 We've patch envers doing this: In AuditedPropertiesReader.addPropertiesFromClass(XClass clazz) we add the condition superclazz != null. private void addPropertiesFromClass(XClass clazz) { XClass superclazz = clazz.getSuperclass(); // superclazz != null applies when superclazz is an interface if ((superclazz != null) && (!"java.lang.Object".equals(superclazz.getName()))) { addPropertiesFromClass(superclazz); } addFromProperties(clazz.getDeclaredProperties("field"), "field", fieldAccessedPersistentProperties); addFromProperties(clazz.getDeclaredProperties("property"), "property", propertyAccessedPersistentProperties); }
