We have a third party application which uses Java 1.5.x, ojdbc5 and Oracle 11g. We cannot change the Java version so cannot change the jdbc driver. We need to upgrade to Oracle 12c.
Has anyone seen any issues with using ojdbc5 against an Oracle 12c database. We have verified that there is nothing in the app that would prevent us from using Oracle 12c as all the underlying code uses plain SQL, but don't want to come up with some hidden jdbc issue.
