      Description

      OPENJPA-1400 introduced a bug that can be encountered when reading a streamed object under the following circumstances:

      • Using a serializable DetachedStateManager (<property name="openjpa.DetachState" value="fetch-groups(DetachedStateField=true)"/>)
      • The Entity needs to have a version field AND either:
      • If no inheritance, a 'proxyable' (ie: java.sql.Date, java.util.List) field with a name that is lexicographically after the version field.
      • If using inheritance, a 'proxyable' (ie: java.sql.Date, java.util.List) field in a child class.

      The bug could manifest itself in a number of ways. Below is the one I was able to reproduce.
