       * trigger a failover in a load-balanced deployment.

       * will pass in the Properties, otherwise it acts like a normal Extension.
       * One instance of a handler *per* JDBC connection instance will be created. If
       * you need singleton-like behavior, you're on your own to provide it.

       * @return true if the exception should trigger failover.
