----------------------------------

             Summary: FineGrainedAtomicHashMap should support independent write skew checks for each key
                 Key: ISPN-3123
                 URL: https://issues.jboss.org/browse/ISPN-3123
             Project: Infinispan
          Issue Type: Enhancement
          Components: Fine-grained API
    Affects Versions: 5.3.0.Beta2
            Reporter: Dan Berindei
            Assignee: Mircea Markus
             Fix For: 6.0.0.Final


FineGrainedAtomicHashMap supports fine-grained locking in pessimistic mode, but in optimistic mode the write-skew check is still done for the entire map.

The write skew check should be done for each entry of the map individually, so that multiple transactions can update the same FineGrainedAtomicHashMap at the same time.
