Dennis Reed updated ISPN-5526:
------------------------------
                 Fix Version/s:     (was: 7.0.0.Final)
                                    (was: 6.0.1.Final)
                   Description: 
Same issue as ISPN-3184, but for repl caches in Infinispan 5.2.x.
(ISPN-3184 only fixed dist caches, since repl uses the same code in 5.3+).

AtomicHashMap and FineGrainedAtomicHashMap, as well as custom DeltaAware implementations, use PutKeyValueCommands with the DELTA_WRITE flag to execute incremental updates. These commands need the previous value of the entry in order to work.

If a node is joining and it receives a PutKeyValueCommand with the DELTA_WRITE flag before it has received the value of the affected key, it should do a remote get to retrieve the previous value and apply the change on top of that value, just like we do for conditional commands. Not doing so leads to data loss.

                                    (was: 5.3.0.Final)


Does not affect 5.3+ with ISPN-3184.
