             Summary: FunctionalNonTxBackupOwnerBecomingPrimaryOwnerTest.testPrimaryOwnerChangingDuringRemove random failures
                 Key: ISPN-6040
                 URL: https://issues.jboss.org/browse/ISPN-6040
             Project: Infinispan
          Issue Type: Bug
          Components: Core, Test Suite - Core
    Affects Versions: 8.1.0.Final
            Reporter: Dan Berindei
            Assignee: Galder Zamarreño
            Priority: Blocker
             Fix For: 8.2.0.Alpha1


Similar to ISPN-6039, the test failure is caused by the state transfer put happening after the test's remove.

In this case, the command types are different, so blocking works correctly. However, when the {{ReadWriteKeyValueCommand}} executes before the state transfer put, it doesn't find any value, and it doesn't commit the entry. This means the key is not added to {{CommitManager}}'s {{tracker}} map, and the state transfer put is allowed to write to it - effectively undoing the remove.
