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

             Summary: Possible inconsistency with concurrent transactions during state transfer
                 Key: ISPN-3287
                 URL: https://issues.jboss.org/browse/ISPN-3287
             Project: Infinispan
          Issue Type: Bug
          Components: Locking and Concurrency, State transfer
    Affects Versions: 5.3.0.Final
            Reporter: Dan Berindei
            Assignee: Dan Berindei
             Fix For: 6.0.0.Final


It looks like there is a data race between the state transfer thread and a concurrent transaction in EntryWrappingInterceptor.commitEntryIfNeeded:

tx: commitContextEntry()
ST: stateConsumer.isKeyUpdated(k)? false
tx: stateConsumer.addUpdatedKey(k)
ST: commitContextEntry()

We probably need some synchronization here, maybe using EquivalentConcurrentHashMapV8.computeIfAbsent().
