Error description

• An InvalidStateException is being thrown to the SystemOut.log
  when attempting to persist an entity which contains an
  interface as a persistable field.
  
  Here is the complete stack.
  
  Exception data: <openjpa-1.2.3-SNAPSHOT-r422266:965640
  fatal user
  error> org.apache.openjpa.persistence.InvalidStateException:
  Encountered
  unmanaged object in persistent field
  "com.xx.xxx.res.subscription.
  Subscription._subscriberLocator" during flush.  However, this
  field does
  not allow cascade persist. Set the cascade attribute for this
  field to
  CascadeType.PERSIST or CascadeType.ALL (JPA annotations) or
  "persist"
  or "all" (JPA orm.xml), or enable cascade-persist globally, or
  manually
  persist the related field value prior to flushing. You cannot
  flush
  unmanaged objects or graphs that have persistent associations to
  unmanaged objects.

Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM ‚ ® WebSphere ‚ ® Applicatio
  *                  Server V7.0.0 whose entity contains a       *
  *                  serializable object which in turn           *
  *                  implements an interface.                    *
  ****************************************************************
  * PROBLEM DESCRIPTION: InvalidStateException is thrown when    *
  *                      persisting a serializable which         *
  *                      implements an interface.                *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  Take the following pseudo code:
  
  public interface ICar extends Serializable {...}
  
  public class CarImpl implements ICar {...}
  
  @Entity
  public class MyEntity implements Serializable {
     protected ICar _car;
     ...
  }
  
  
  If a user has code similar to the above, when persisting a
  'MyEntity', an InvalidStateException will be thrown given the
  class/interface hierarchy.  OpenJPA doesn't recognize the type
  of the ICar persistable field as being an interface.
  

Problem conclusion

• With this fix, code has been added to ensure that a
  persistable field which is an interface is properly recognized
  and persisted.
  
  The fix for this APAR is currently targeted for
  inclusion in Service Level (Fix Pack) 7.0.0.17 of WebSphere
  Application Server version 7.0.0.
