The knowledge cache previously used a synchronized IdentityMap to cache knowledge indexes. ConcurrentHashMap was not used because computeIfAbsent needed to be called recursively when creating indexes, and that doesn't work with ConcurrentHashMap. However, ConcurrentSkipListMap can be work with recursive calls to computeIfAbsent.
