Description

    def immutableListenerConfigs(kafkaConfig: KafkaConfig, prefix: String): Map[String, AnyRef] = {
      newConfig.originals.asScala.filter { case (key, _) =>
        key.startsWith(prefix) && !DynamicSecurityConfigs.contains(key)
      }
    }

We don't actually compare new configs to origin configs so the suitable exception is not thrown.
