Axel Howind deleted comment on MATH-1561:
-----------------------------------
was (Author: axh):
I think we really need a commons-math3 release that has at least an automatic
module-name set while we wait for a stable release 4. And I hope version 4 will
not only add an automatic module name but a real module-info.class so that it
is usable with jlink.
Currently commons-math3 is the most painful dependency in any project I have
because of missing module support. I cannot just replace it because it is a
dependency of other projects I use, Apache POI being the most prominent one.
If you need any help either with adding a module-info or any other issues
standing in the way of releasing version 4, I'm willing to contribute.
