Robert Muir commented on LUCENE-5623:
-------------------------------------
Thanks Mike!
I think currently you have to get way too unlucky to find this bug. Maybe its
due to the random distribution of integers being used and so on. I will try to
make the test more evil. Really this thing should be failing left and right,
its not very effective right now.
