[jira] [Created] (ZOOKEEPER-3981) Flaky test MultipleAddressTest::testGetValidAddressWithNotValid

Michael Han created ZOOKEEPER-3981:
--------------------------------------

             Summary: Flaky test MultipleAddressTest::testGetValidAddressWithNotValid
                 Key: ZOOKEEPER-3981
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3981
             Project: ZooKeeper
          Issue Type: Task
          Components: tests
            Reporter: Michael Han
            Assignee: Michael Han


Problem:

Test MultipleAddressTest::testGetValidAddressWithNotValid might fail deterministically when the address it's using, 10.0.0.1, is reachable, as per https://tools.ietf.org/html/rfc5735 10.0.0.1 might be allocatable to private network usage. In fact, the router address of my ISP is assigned this IP, leading to this test always failing for me. 

Solution:

Replace the address with 240.0.0.0, which is reserved for future use and less likely to be reachable.
