Does anyone else have the same problems?

On my system java-testng sometimes fails nondeterministically within
the check phase:

Do others experience this too, or is it just my machine?

On berlin, everything looks fine, that makes we wonder:

https://ci.guix.gnu.org/search?query=3D%5Ejava-testng

We had some problems in the past with other parallel tests:

https://debbugs.gnu.org/cgi/bugreport.cgi?bug=3D30526

I also tried to update java-testng but that was not possible quickly,
because of new/updated dependency-graph.

During my work on getting a maven-build-system, I recently rebuilt testng =

During today's regular "guix pull", I ran into this problem: java-testng
failed to build twice (the failures comes from the test suite), but
built correctly the third time. That's for commit:
39fa1ef033fda82cb1d122e0d1675b51acb1db34

Cheers,
  Konrad.
