feel free to update the year once enough copyrightable changes were done
fix reproducible builds
An alternative approach would be if you just build JNA with the property set:
ant -Dyear=2016 dist
Any problem with that?
see also https://reproducible-builds.org/ . It would be nice to have this by default without all the distributions individually having to find out about this option and patch it.
apart from that there is also the legal aspect when I build today's software unchanged in 2018, that it claims copyright for 2018 even though no author changed anything. That somehow feels wrong.
Ok - I can see the argument. Merged.
