This should be fixed in 892a5647debc7fe8eafac4f725c46134eb085b63.

I was cramming the whole set of dependencies for maven in the
classpath, but it seems it doesn't play well with downloaded plugins.
Now I generated a m2.conf file with multiple "load" lines to tell
plexus-classworlds where to find the required jar files.

So I've tested this, and it turns out it's not our package's fault: it
fails undeterministically also when using the system's maven. I fixed
it by downgrading maven-surefire-plugin version to 2.20 instead of
2.20.1.

Thank you for your reports! Do you think we can close this report now?
