Sounds promising ... could you provide a link?  I'm quite inexperienced with this level of software acquisition. Before I posted I tracked down a jogl 2.4 mac os build from April 10 2019 at this URL:
https://jogamp.org/chuck/job/jogl/lastSuccessfulBuild/label=macosx-10_6-x86_64-nvidia/
and this build file:
        jogl-2.4-b1483-20190410-macosx-universal.7z
but when I tried to uncompress it I got the error message "the archive file is incomplete".
So I gave up and made my post.
