send message error: No route info of this topic,

[ausky]

my schedule application have 1000+ rmq task , which task with a different topic , so my app contains 1000+ topic info ；

MQClientInstance

this.scheduledExecutorService.scheduleAtFixedRate(new Runnable() {

            @Override
            public void run() {
                try {
                    MQClientInstance.this.updateTopicRouteInfoFromNameServer();
                }
                catch (Exception e) {
                    log.error("ScheduledTask updateTopicRouteInfoFromNameServer exception", e);
                }
            }
        }, 10, this.clientConfig.getPollNameServerInteval(), TimeUnit.MILLISECONDS);

MQClientInstance will get all topic routeinfo from nameserver per 30s ；

when MQClientInstance's scheudle is running ,then a now topic task coming , my app will call send , the Producer send will also call updateTopicRouteInfoFromNameServer

public boolean updateTopicRouteInfoFromNameServer(final String topic, boolean isDefault, DefaultMQProducer defaultMQProducer) {
        try {
            if (this.lockNamesrv.tryLock(LockTimeoutMillis, TimeUnit.MILLISECONDS)) {
                ...

this method will lock ;

private final Lock lockNamesrv = new ReentrantLock();

lockNamesrv is noaffair lock ，this will case new topic's send can't get lock ,then throw exception No route info of this topic

why lockNamesrv not use affair lock ？
