This is an implementation detail. For a distributed data structure it will never be a CAS loop because we always acquire a lock for the corresponding cache entry and then run an entry processor. Agree with Sergi, I would rather name it getAndUpdate to be consistent with java AtomicLong since this is the class which IgniteAtomicLong was mimicking in the first place.
