Symptoms

With Oracle 19.3 JDBC driver, AC/Replay does not work against a 12.2.x database. An NPE is thrown during the replay process. Please see the complete exception stack below.

The following is observed:
- With the old 18c JDBC driver and 12.2.x database, the replay test passed.
- With the 19.3 JDBC driver and 19c database, the replay test passed.
- With the 19.3 JDBC driver with a 12.2.x database, the replay fails.

Note: Switching the ojdbc8.jar back to version 18.3 solves the issue.
