Oracle dialect for Oracle12c database

Question

So far we have been using the dialect org.hibernate.dialect.Oracle9Dialect for hibernate.dialect property for all Oracle versions (10g/11g). We plan to use Oracle12c as well. Our initial tests indicate that continuing with Oracle9Dialect for Oracle12c will work. Does anyone have any suggestions/ recommendations/use cases where we would need to use a different dialect for Oracle12c while maintaining backward compatibility with earlier Oracle versions (10g/11g) ?

It would be great if some one can point me to an existing wiki/documentation which I might have missed on oversight.

Answer 1

I was using the Oracle10gDialect, but Jboss 6.1 failed to start properly. I had to remove Hibernate 3.6.6 and install Hibernate 4.2.15 and make a few code changes to properly support 12c. To be clear, I think the old dialect would work, but JBoss didn't seem to like it.
