我有一点点不理解的地方，按照正常的来说，我们ReferenceCountExchangeClient关闭了之后会调用replaceWithLazyClient，这时候会将ReferenceCountExchangeClient中的client替换成LazyConnectExchangeClient，在下次调用的时候，referenceCountExchangeClient
== null || referenceCountExchangeClient.isClosed()
走到这个判断，会调用到LazyConnectExchangeClient的isclose。这时候LazyConnectExchangeClient的client为null
，导致返回false。使得一直使用的都是调用是LazyConnectExchangeClient的client为null
的Client，这时候，LazyConnectExchangeClient
request会一直initClient。我有点不是太理解，我看我之前用的2.7.3.1的时候，这时候LazyConnectExchangeClient的client为null会返回true，导致他会调用buildReferenceCountExchangeClient
重新new ReferenceCountExchangeClient。相比之下，是哪个会更合理点呢？
