Description

DataSerializer contains support for ConcurrentHashMap which is currently disabled in writeObject but enabled in readObject. This means that if we enable the writeConcurrentHashMap, rolling upgrade will still behave correctly because readObject supports reading it in from either Java Serializable or Geode DataSerializer form. Enabling writeConcurrentHashMap improves the performance of Geode messages (such as ParallelQueueRemovalMessage) that have fields of type ConcurrentHashMap or any Collection type containing a ConcurrentHashMap.
