LRA tests can fail if the network is running slowly

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.

ochaloup@redhat.com 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
