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

             Summary: AtomicHashMap.put is not atomic with pessimistic locking
                 Key: ISPN-3124
                 URL: https://issues.jboss.org/browse/ISPN-3124
             Project: Infinispan
          Issue Type: Enhancement
          Components: Core API
    Affects Versions: 5.3.0.Beta1
            Reporter: Dan Berindei
            Assignee: Dan Berindei
             Fix For: 5.3.0.CR1, 5.3.0.Final


When the user calls {{AtomicHashMap.put(k, v)}}, {{AtomicHashMapProxy.getDeltaMapForWrite()}} first reads the atomic map in the invocation context, and only acquires a lock afterwards.

Between the read and the lock, another transaction can write something to the atomic map, and that write will be lost.
