[news.eclipse.rt.eclipselink] problem with DB2 database - DB2 urgent

[ajayara1@xxxxxxxxxxx (Ajay Kumar)]

I have following relationship in the three class 

----
Entity A

@Entity
@Table(name = "B")
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name = "FIELDID", discriminatorType = 
DiscriminatorType.INTEGER, length = 4)
@DiscriminatorValue(value = "0")
public class C {

-------------
----
Entity D{
@Entity
@Table(name = "E")
@AttributeOverride(name = "name", column = @Column(name = "vuiName"))
private class C
}

-------------

Following JPA query is created 
SELECT v.schemaId, v.vuiId, v.vuiType, v.locale, d.label, d.propShort, 
d.propLong FROM D v, C d WHERE (d.vuiId = v.vuiId) AND (d.schemaId = 
v.schemaId) AND (d.fieldId = 0) ORDER BY v.schemaId

While running the above jpa QL the following two  sql are created

1) is OK
[EL Fine]: 2009-07-20 
22:08:49.205--ServerSession(9582794)--Connection(12851324)--Thread(Thread[main,5,main])--SELECT 
t0.SCHEMAID, t0.VUIID, t0.VUITYPE, t0.LOCALE, t1.LABEL, t1.PROPSHORT, 
t1.PROPLONG FROM E t0, B t1 WHERE ((((t1.VUIID = t0.VUIID) AND 
(t1.SCHEMAID = t0.SCHEMAID)) AND (t1.FIELDID = 0)) AND (t1.FIELDID = 0)) 
ORDER BY t0.SCHEMAID ASC

[EclipseLink-4002] (Eclipse Persistence Services - 1.1.2.v20090612-r4475):

Internal Exception: com.ibm.db2.jcc.b.SqlException: DB2 SQL error: 
SQLCODE: -401, SQLSTATE: 42818, SQLERRMC: =
Error Code: -401
2) Wrong sql becasue considering fieldid as character 
Call: SELECT t0.SCHEMAID, t0.VUIID, t0.VUITYPE, t0.LOCALE, t1.LABEL, 
t1.PROPSHORT, t1.PROPLONG FROM E t0, B t1 WHERE ((((t1.VUIID = t0.VUIID) 
AND (t1.SCHEMAID = t0.SCHEMAID)) AND (t1.FIELDID = '0')) AND (t1.FIELDID = 
'0')) ORDER BY t0.SCHEMAID ASC

This issue is blocking us any suggestion.
