             Summary: ConsistentHashV1IntegrationTest.testCorrectBalancingOfKeysAfterNodeKill random failures
                 Key: ISPN-3325
                 URL: https://issues.jboss.org/browse/ISPN-3325
             Project: Infinispan
          Issue Type: Feature Request
          Components: Test Suite
    Affects Versions: 5.3.0.Final
            Reporter: Dan Berindei
            Assignee: Mircea Markus
             Fix For: 6.0.0.Final


The test adds a 5th server, but {{ConsistentHashV1IntegrationTest.getHitServer()}} assumes that the requests hit one of the original 4 servers. Because the server CH to client CH is imperfect in protocol versions 1.1 and 1.2, some of the requests may instead hit server 5, causing a {{NullPointerException}}:
