The earlies downloadable JDBC driver is 11.2.0.4 on Oracle's
page (https://www.oracle.com/technetwork/database/application-development/jdbc/downloads/index.html).
Additionally in a Linux install script there was a copy-paste issue.

(Is it possible to move the project to GitHub? Creating a fork takes an hour. This issue tracker is very slow too.)
Oracle finally has some drivers available in Maven Central; we have updated to use those.
