      Description

      expected += ClassSize.estimateBase(ConcurrentSkipListMap.class, false);
      expected += ClassSize.estimateBase(ConcurrentSkipListMap.class, false);
      expected += ClassSize.estimateBase(CopyOnWriteArraySet.class, false);
      expected += ClassSize.estimateBase(CopyOnWriteArrayList.class, false);
      

      We need to consider the heap requirement for KeyValueSkipListSet.
      From where CopyOnWriteArraySet & CopyOnWriteArrayList is coming into picture? I am not able to follow.
      Also we need to consider the heap for TimeRangeTracker
