[jira] [Commented] (CASSANDRA-16229) Flaky jvm-dtest:
org.apache.cassandra.distributed.test.ring.NodeNotInRingTest.nodeNotInRingTest
[ https://issues.apache.org/jira/browse/CASSANDRA-16229?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17268131#comment-17268131 ]

The test was manually removing endpoints from the gossiper and doing endpoint cleanup incorrectly - after notifying StorageService about a change in state, it should handle all this as necessary. Doing it manually creates a race somewhere.
