Configuration.setConsistentHashClass not working
------------------------------------------------

                 Key: ISPN-422
                 URL: https://jira.jboss.org/jira/browse/ISPN-422
             Project: Infinispan
          Issue Type: Bug
          Components: Configuration, Distributed Cache
    Affects Versions: 4.1.0.ALPHA3, 4.0.0.Final
            Reporter: Galder Zamarreno
            Assignee: Galder Zamarreno
             Fix For: 4.1.0.BETA1


Consistent class cannot be defined via configuration. Doing so throws:

This is because the field name provided to testImmutability call in setConsistentHashClass is "class". Hence, it tries to override a field called "class" which does not exist. Making the field "consistentHashClass" fixes the issue.
