                 Key: OPENJPA-827
                 URL: https://issues.apache.org/jira/browse/OPENJPA-827
             Project: OpenJPA
          Issue Type: Improvement
          Components: jpa
    Affects Versions: 1.2.0
         Environment: JPA 1.2 running in Tomcat 6.14
            Reporter: Benjamin Renaud
            Priority: Minor


When you have Entity A with a single-table inheritance strategy it would be nice if, when modeling B, C, D ... as subclasses of A JPA would make sure that there are no two columns with clashing names and incompatible types. For example, if B has a field Date defaultValue and C has a field Long defaultValue.
