Batch reading request doesn't prefix field names by table name

Question

A batch reading request doesn't prefix field names by table name and I've got a AmbigiousException which is normal because there is the same fields in the 2 tables.
The following code :
//call a ReadAllQuery and return a list of AffaireImpl
List<Affaire> listeAffaire =  affaireDao.getAffaireCorrespondantes(lccJrd, lnaAnnee, lnaOrdre, lcNataffCode, lnaNoSuite);
for (Affaire affaire : listeAffaire) {
   //there is a one to Many mapping on Affaire to Dossier, with Transparent Indirection, Read-Ony and Batch Reading
   //this metod generate the wrong batch reading method
   List<Dossier> listeDossiers = affaire.getDossier();
generates the following requests:
ReadAllQuery(eu.curia.litige.model.AffaireImpl) --
SELECT * FROM LA_AFF WHERE ( ((LCC_JRD = 'C') AND (LNA_ANNEE = 8)) AND (LNA_ORDRE = 8))
ReadAllQuery(eu.curia.litige.model.DossierImpl) --
SELECT t0.*
FROM LA_DOSSIER t0, LA_AFF t1
WHERE
(((t0.LNA_NO_SUITE = t1.LNA_NO_SUITE) AND ((t0.LCC_JRD = t1.LCC_JRD) AND ((t0.LC_NATAFF_CODE = t1.LC_NATAFF_CODE) AND ((t0.LNA_ANNEE = t1.LNA_ANNEE) AND (t0.LNA_ORDRE = t1.LNA_ORDRE)))))
AND UPPER(LCC_JRD) = 'C' AND UPPER(LNA_ORDRE) = '8' AND UPPER(LNA_ANNEE) = '8')+
but the request should be :
SELECT t0.*
FROM LA_DOSSIER t0, LA_AFF t1
WHERE
(((t0.LNA_NO_SUITE = t1.LNA_NO_SUITE) AND ((t0.LCC_JRD = t1.LCC_JRD) AND ((t0.LC_NATAFF_CODE = t1.LC_NATAFF_CODE) AND ((t0.LNA_ANNEE = t1.LNA_ANNEE) AND (t0.LNA_ORDRE = t1.LNA_ORDRE)))))
AND t1.LCC_JRD = 'C' AND t1.LNA_ORDRE = '8' AND t1.LNA_ANNEE = '8')+
It's strange because this is the only place the batch reading doesn't prefix and uses a UPPER.
For now we have disabled the batch reading, but it decreases the performanes (the list of affaire can be hudge).
Any Idea?
We use TopLink 10.1.3 on a Oracle 10g Database.

Here the mapping (I've also remove the tags of some of the direct mapping fields to simplify the reading)
