Hi Til, I had a brief look at the internets and found some interesting commentary on the subject. https://reproducible-builds.org/docs/deterministic-build-systems/
I didn't spend much time, but there are a few things that I took away from that. I think that Java makes it easier because given any machine supporting Java (specific version) will produce reproducible results if some rules are followed. This is not the case for other compilers that actually might produce different results on different machines. Anyway, I still think it's good to verify reproducible results in our project.
