    Fix Version/s: antlr-rework

Yes, this one is annoying.  However it :
1) is nearly impossible to fix without major changes
2) has a trivial workaround : use named parameters

> The HQL query 
> from Assoc a where a.type.oid = ? and a.constituents[?].oid = ?
> gets translated into
> select
>         reorderedp0_.oid as oid1_,
>         reorderedp0_.type_oid as type2_1_
>     from
>         Assoc reorderedp0_,

>         and constituen1_.constituents_oid=reorderedp2_.oid
>         and reorderedp0_.type_oid=?
>         and reorderedp2_.oid=?
> Where clearly the first and second parameters (the index and the type) have been permuted.
> The relevant thread in the User forum is : http://forum.hibernate.org/viewtopic.php?t=979832
> Attached are a java source file that demonstrates the error, and a zipped maven2 project that supplies the Hibernate, Hibernate-Annotation, H2, and Log4J dependencies.
