    Description

      With the feature Consistent Read from Standby now in branch-2, I found it breaks the build when building with JDK7, because it uses java.util.concurrent.atomic.LongAccumulator which is only in JDK8 and above.

       

      We should figure out if we want to fix it, or give up JDK7 compatibility.
