Attempting to returning a list over RMI/IIOP results in serialization exception
-------------------------------------------------------------------------------

                 Key: OPENJPA-1060
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1060
             Project: OpenJPA
          Issue Type: Bug
          Components: jpa
    Affects Versions: 2.0.0
         Environment: JEE
            Reporter: Jeremy Bauer


Returning a result list over RMI/IIOP invocation currently fails on trunk/2.0 with this exception:

java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.MarshalException: CORBA BAD_PARAM 0x4f4d0006 Maybe; nested exception is: java.io.NotSerializableException:
org.apache.openjpa.jdbc.kernel.InstanceResultObjectProvider is not serializable at com.ibm.CORBA.iiop.UtilDelegateImpl.wrapException(UtilDelegateImpl.java:748)
at javax.rmi.CORBA.Util.wrapException(Util.java:296) at ...

The problem is the result of storing the ROP in the userObject field of a ResultList in the
org.apache.openjpa.kernel.QueryImpl.toResult(..) method.  - res.setUserObject(rop).  The ROP
is not serializable so the RMI/CORBA layer throws an exception.
