   thanks for the review. after write a jmh test it seems the performance not 
that good if LongAdder `add` and `get` have 1:1 access call.
   
   the jmh test here.

   the result 
   
   Benchmark                  Mode  Cnt   Score   Error   Units
   IteratorTest.longAdder    thrpt   25  40.073 ± 0.443  ops/us
   IteratorTest.longCounter  thrpt   25  41.377 ± 1.111  ops/us
