Description of problem: DistTopologyChangeUnderLoadTest.testPutsSucceedWhileTopologyChanges fails randomly, see http://10.3.10.33:8081/view/4_JDG_6_5_x/job/JDG_6_5_x_Nightly/292/testReport/junit/org.infinispan.client.hotrod/DistTopologyChangeUnderLoadTest/testPutsSucceedWhileTopologyChanges/
In my opinion this test might occasionally fail since we use there TestingUtil.sleepThread(2000). I think it should be rewritten and it should use some kind of Barrier or CountDownLatch for synchronizing.
