title: How to change default JDBC driver of Oracle SQL Developer?
body: <p>I have an old Oracle 9i r2 database. The last JDBC driver that I managed to make work with it is ojdbc6 11.2.0.4. This keeps me stuck to SQL Developer 4.0.3. I would like to benefit from features of newer versions of SQL Developer. But they use newer driver like ojdbc8.</p>
  <p>Is there a way to use old drivers with new versions of SQL Developer? The option to add third party JDBC drivers only work to add drivers for other databases like db2 or sql server.</p>
  <p>I tried to delete the recent driver and replace it by an older one but SQL Developer malfunctions.</p>
