> Some internal legacy data structure are replaced with Java collection:
> # Remove redundant {{AbstractConcurrentMapBase}} and {{AbstractConcurrentMap}}, and their related inner classes, e.g. {{Entry}}
> # Make {{ManagedConcurrentMap}} based on {{ConcurrentHashMap}}, which is much more mature than the original one
> Though the some classes are removed and some methods are renamed, they are internal *runtime* API, so the changes shoud not break users' existing code.
