#9284 修改了ReferenceCountExchangeClient的replaceWithLazyClient方法，在创建LazyConnectExchangeClient之前增加了RpcContext.getServiceContext().getConsumerUrl()非null判断，为null则直接返回以避免NPE。 存在的不足： 1. 不容易理解； 2. 不通用：严格意义上目前只有InstanceAddressURL类型的URL才会出现NPE，如果只对InstanceAddressURL类型的URL做上述判断，dubbo-rpc-dubbo要增加dubbo-registry-api依赖，然后ReferenceCountExchangeClient才能使用InstanceAddressURL类型进行判定。 如果能直接获得当前ScopeModel的destroyed状态就好了，用destroy状态进行判定不仅容易理解，而且更支持URL类型扩展。 -- This is an automated message from the Apache Git Service.
