Hi,
this is the MacOS virtualbox. This one often hast timeshifts caused by
Virtualbox and the NTP daemon of OSX is bullshit (no chrony).
Actually earlier versions of MacOS had a bug in their OS libc
segfaulting the app to crash on backwards jumps of wall time, which was
fixed a few years ago. Now it looks like sometimes only Gradle/Java
hangs because of this. Macos and backwards-jumping time do not fit well!
Maybe a reason why Apple does not like their OS virtualized :-) Their
bullshit kernel only works for 100% INTEL CPUs with all hardware
behaving exactly in order to time.

Damn. I know about it but never had it happen to me. You're right in
that it could be a reason and it's definitely one of the aspects I can
take off the checklist. It looks strange because those timeouts are
fairly high - the time correction would indeed have to be significant
for this to fail (and in the middle of the process?!). Anyway, I'll
look into this - thanks for the pointer!

Hi Dawid, I looked at this and also https://github.com/apache/lucene/issues/7687
If you look at the instances and how sporadic they are, the problem
could be caused by TimeoutSuite using wall-clock time in
com.carrotsearch.randomizedtesting? Especially in virtual machines,
wall-clock time can be extremely inaccurate when you spin them up,
then there's a big correction (via NTP or VM agent).
I have no proof this is what is happening, except to say, I think it
would be better if randomizedtesting used monotonic time (nanoTime)
rather than wall-clock time (currentTimeMillis). It would make it more
robust.

A test timed out. I've beasted with the same settings but can't
reproduce. Either JVM bug somewhere or cosmic interference...
