Jeremy Bauer resolved OPENJPA-1060.
-----------------------------------
Resolution: Fixed
Fix Version/s: 2.0.0
Resolved by making the opaque user object within the result list transient.
This prevents the object from being serialized along with the result list.
> Attempting to returning a list over RMI/IIOP results in serialization
> exception

> 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.
