   1. DubboProtocol在关闭的时候，会对持有的SharedClientsProvider进行销毁；
   2. 
但是在这之后，DubboProtocol会调用父类AbstractProtocol对当前协议下的Invoker进行销毁，而在dubbo协议对应的DubboInvoker中，又会对持有的ClientsProvider（可以是SharedClientsProvider）再次进行销毁；
   
   这个情况是合理的吗？在2.7.15版本和3.3版本都对比过，是类似的逻辑；
   
   而这个问题会导致ReferenceCountExchangeClient内部，及相关底层类的close被二次调用
   
   附上相关代码：
   DubboProtocol的销毁：
