[jira] Resolved: (OPENJPA-42) Simple orm.xml file causes exception
(NPE)
[ http://issues.apache.org/jira/browse/OPENJPA-42?page=all ]
Marc Prud'hommeaux resolved OPENJPA-42.
---------------------------------------
Resolution: Fixed
The error message is a bad one (which I've committed a fix for), but the cause of it is that the orm.xml file is in error: as I mentioned in OPENJPA-40, the attribute-override element is, AFAIK, only meant to be used to redfine a field declared in a superclass entity. Since Manager doesn't actually have any Entity superclass, OpenJPA's assumption was causing an NPE. A better error message will now be thrown.
