-------------------------------------
Summary: NPE during enhancement processing
Key: OPENJPA-2331
URL: https://issues.apache.org/jira/browse/OPENJPA-2331
Project: OpenJPA
Issue Type: Bug
Components: Enhance
Affects Versions: 2.0.1, 2.0.2, 2.0.3
Reporter: Kevin Sutter

with the child class. These errant attributes caused the issues with the
enhancement processing.
So, a combination of the migration tools along with the mixed up orm xml files
led to these errors. But, still an NPE is not good and we should handle these
conditions better. Thus, this JIRA...
