      Description

      Current implementation of MapWritable uses HashMap as Map implementation. But in some of the use cases we need other implementations of Map like LinkedHashMap,SortedMap.This jira changes visibility of 'instance' in MapWritable from private to protected which allows us to inject custom Map implementation through sub classing MapWritable .
