      Description

      SpecIT#acceptTest failed on CI (http://narayanaci1.eng.hst.ams2.redhat.com/job/narayana/PROFILE=MAIN,jdk=jdk8.latest,label=linux/187/) and on one of the PRs.

      Ondrej Chaloupka did some investigation:

      I did some experiments with the lra testing and normally tests pass on my laptop. But as you mentioned it's probably timing issue as when I slow down the network (I used tc as described at [1]) then the tests started to fail[2] (I'm on master branch).

      Do you think you can check it on your laptop if you can see the same issue? Or how to manage that?

      Thanks
      o.
