Why does Java 8 provide LongAccumulator but not IntAccumulator?

Currently my program makes heavy use of AtomicInteger

to keep track of the execution of maximum int values ​​that are reported in parallel.

After reading about Java 8 new LongAccumulator

s, I was hoping to use IntAccumulator

s max

as an accumulator function to accomplish my desired behavior with less thread conflicts. However, it doesn't seem to exist.

Is there any reason that IntAccumulator

doesn't make sense? It seems plausible to me that there may be low-level instructions that make it unnecessary IntAdder

, but IntAccumulator

may represent more behavior than can be captured by a low-level instruction.

(If it matters at all, I intend to use them from Scala code)
