      boolean shouldExceptionTriggerFailover(SQLException ex)
      Invoked to determine whether or a given SQLException should trigger a failover in a load-balanced deployment. The driver will not pass in a Connection instance when calling init(), but it 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.
      Parameters:
      ex -
      Returns:
      true if the exception should trigger failover.
