On the Windown build I have seen this error on Jenkins:

Looks like the NRT test does not pass the full JVM command line. I won't
change this in the PR, but add some workaround.
Interestingly it did not fail on my local Windows and also not on Linux
Jenkins. So it seems to be that the parent test does not even pass all system
properties to the underlying test, so it uses directory randomization, although
Jenkins hardcoded `-Dtests.directory=MMapDirectory`. This is why it does not
fail consistently.
