> 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.
