    Description

      There is a classpath scanning machinery inside ClassNameCompleter.

      I think the sole purpose of these things is to scan for jdbc drivers...(but not entirely sure)

      if it is indeed looking for jdbc drivers..then possibly this can be removed without any issues because modern jdbc drivers usually advertise their driver as a service-loadable class for java.sql.Driver
