I was able to apply this patch on current master
ec6122250de7c83a7e77054584a34767b11337db ... and successfully build
java-xalan-interp!

But this appears to add java-xalan-interp, but the subject is "Add
java-xalan".

I'm not confident in reviewing the whole patch series, and not terribly
savvy with guile or java ...

The patches started in 2018, are some of the earlier patches applied?
Are there other patches that still need applying? Or can they be
dropped?

Do you have a summary of the discussion around licensing and other
issues? Makes me a bit nervous to apply patches as the current status is
not totally clear to me.

If these aren't the first generation patches in the series, maybe
re-send the patches that still need applying as a [PATCH v2] (or v3?
v4?) in the subject of each patch?


With a summary clarifying the licensing and which exact patches still
need applying, that would make it a lot easier to review!


Thanks for contributing to guix, and hanging onto patience with the
process!


live well,
