Github user justinleet commented on the issue: https://github.com/apache/incubator-metron/pull/463 Are we settling on "less sporadic"? Like I noted in the ticket, I had the original test run for over a minute (~90 seconds) before the JVM decided to actually be single threaded. It's not the usual case but I probably only ran it 20 or so times before I hit the 90 second case. It seems more likely to fail in Travis, which is fine, but I'm not sure I want my local build failing that often.
