JDK 10 RFR of 8176894: Provide specialized implementation for default methods putIfAbsent, computeIfAbsent, computeIfPresent, compute in TreeMap

[Tagir F. Valeev]

Hello!

Great and long-awaited feature, thanks!

I don't see that modCount is checked after calling mappingFunction in
compute/computeIfAbsent/computeIfPresent. Is it possible to break the
Map if mappingFunction changes the Map content? See similar problems
in HashMap:

With best regards,
Tagir Valeev.
