[classlib][luni][performance] ObjectInputStream should use HashMap instead of Hashtable for
internal storage
------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-5634
                 URL: https://issues.apache.org/jira/browse/HARMONY-5634
             Project: Harmony
          Issue Type: Improvement
            Reporter: Aleksey Shipilev


For now, ObjectInputStream uses Hashtable for two storages:
 1. static PRIMITIVE_CLASSES, populated via static initializer, read by all instances (e.g.
in theory by all threads)
 2. private objectsRead, serving as instance-local buffer

Both of these storages should be migrated to HashMap, since Hashtable.get is synchronized
and synchronization is not needed here.
