According to the What's new in 4.2 SP5, and the new section in the oracle.sbo in the jdbc data access, there is technically a new database section called
<DataBase Active="Yes" Name="Oracle 12c Release 2">
While earlier Oracle JDBC entries were ojdbc6.jar for Oracle 11 and prior, and I was able to get away with using ojdbc7.jar for the Oracle 12c release entry. Technically the ojdbc8.jar entry is the one from oracle that is the Oracle 184.108.40.206 12c R2 version. Is this now supported, or should we still be using the ojdbc7.jar against the R2 version? I know there has been incompatabilities in prior versions.
