   DefaultMQPushConsumer::start() will call MQClientFactory::updateTopicRouteInfoFromNameServer() -> ... -> TcpRemotingClient::invokeSync() -> ... -> TcpTransport::connect() -> TcpTransport::getInetAddr(). If host cannot be resolved, evutil_getaddrinfo() will return error, then throw MQClientException. In call chain, nobody catch the exception.
