    Description

      The TableRateStatistics non-static data member in ConcurrentHashtable and uses 8 pointer sized words. If a table doesn't report this, this field should be optional. When changing Dictionary to ConcurrentHashtable, there's one per ClassLoaderData for non-hidden class loaders so this footprint increase may be noticed.
