Review comment:
Ah, so this is just for that special case. No problem, now I understand!
I remeber this one was always also a problem with the Maven build (for
non-modular reasons) so we had those fake projects with only tests or only
main, just to break the circular dep.
So in short Lucene core tests will run fully non-modular (testframework,
core, codecs all on classpath)?
