             Summary: clusterName=null causes NPE or hanging at JGroups startup 
                 Key: ISPN-1858
                 URL: https://issues.jboss.org/browse/ISPN-1858
             Project: Infinispan
          Issue Type: Enhancement
          Components: Core API
    Affects Versions: 5.1.1.FINAL
            Reporter: Thomas Fromm
            Assignee: Manik Surtani


When configuring the cache programmatic using the GlobalConfigurationBuilder and setting the clustername to null,
causes JGroupsTransport to hang at startup or creating NPE, when JMX is enabled.
