    Description

      Thin client protocol handler for Put_All (1004) operation will create a linked hash map and then invoke putAll on this map.

      This leads to couple of issues:

      • Thin client may easily deadlock the cluster by issuing parallel transactional putAlls with different order of keys.
      • "Unordered map with putAll" warning is printed to log, causing user confusion, even if client actually uses SortedMap with putAll().

      What we really need is BinaryObject-aware SortedMap / making sure that keys/KeyCacheObjects are always comparable.
