A candidate replacement for java.util.concurrent.ConcurrentHashMap
is now available as jsr166e.ConcurrentHashMapV8. This version
is much more amenable to upcoming support for aggregate
parallel operations (including, already, method "computeIfAbsent'
using a stand-in MappingFunction type).

The internal design is interestingly different.
Read the internal documentation for details.

Please give it a try, and let us know about experiences.
