I am no longer able to run multiple simulations in parallel using Tester.scala.
Since it fails when I run jobs in parallel, but not serially, I assume a race condition was
introduced in Tester.scala somewhere.
Sometimes the bug causes the simulation to give wrong results,
sometimes I get the below stack trace.
I might try to narrow the issue down further or create an easily reproducible case later.
