再说一下this.connectivityCheckFuture被创建的新任务重新赋值的问题： checkConnectivity异步创建的任务在结束前判断是否有新task，如果有就再次调用checkConnectivity： 1. this.connectivityCheckFuture在checkConnectivity方法返回调用者之后又被更新，调用者并不知情； 2. 调用者在旧的connectivityCheckFuture上等待的结果就是新task未执行完，调用者就继续执行后面的代码，然后出问题，比如： https://github.com/apache/dubbo/runs/4130565263?check_suite_focus=true ``` 2021-11-07T11:46:56.1815610Z [ERROR] Tests run: 3, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 0.19 s <<< FAILURE! - in org.apache.dubbo.rpc.cluster.support.ConnectivityValidationTest 2021-11-07T11:46:56.1818867Z [ERROR] org.apache.dubbo.rpc.cluster.support.ConnectivityValidationTest.testRetry Time elapsed: 0.007 s <<< FAILURE! 2021-11-07T11:46:56.1820680Z org.opentest4j.AssertionFailedError: expected: <2> but was: <1> 2021-11-07T11:46:56.1822662Z at org.apache.dubbo.rpc.cluster.support.ConnectivityValidationTest.testRetry(ConnectivityValidationTest.java:190) ``` -- This is an automated message from the Apache Git Service.
