> 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 .
