Description

TestAtomicOperation.testMultiRowMutationMultiThreads deadlocks.

There is an easy fix for the test that synchronizes on the CHM instead of the object. We already have a Findbugs exceptions for synchronization on the CHM and get-then-set on it is what we synchronizing for anyway.

This is only relevant for branch-1 because we have to synchronize get-then-set due to Java 7 compatibility. For branch-2 and master we use CHM#computeIfPresent.
