             Summary: NPE in SingleFileStore
                 Key: ISPN-3506
                 URL: https://issues.jboss.org/browse/ISPN-3506
             Project: Infinispan
          Issue Type: Bug

    Affects Versions: 6.0.0.Alpha4
            Reporter: Michal Linhard
            Assignee: Mircea Markus


SingleFileStore doesn't count with expired entries and causes NPE when entrySet is called.
