    Description

      Specialized implementations for putIfAbsent, merge, compute, computeIfAbsent and computeIfPresent in TreeMap class were created (JDK-8176894). However, derived maps like TreeMap.descendingMap(), TreeMap.subMap(), TreeMap.headMap(), etc. still have default implementation. It looks fairly straightforward to provide these implementations.
