Hi Amit,
please use the developer list for such concerns, which I've added in CC.

Personally I don't think your issue is valid, but I'll leave that to
the other team members to decide.
We never promised backwards compatibility with other frameworks when
upgrading from Hibernate 3 to 4, it is likely that you will need to
make some adjustments in configurations; also I'm not a Spring expert
but from what you describe it looks to me it's not a good idea to use
the "spring jdbc template" as JDBC and Hibernate are two different
things.
