Thanks for the answers. I'm looking forward to the release then, to see the process cycle complete. :)
I would love to use the cherry-pick.sh for also pushing to the branch, but it fails on my machine / Windows when it tries to run the tests (probably some gradlew / gradlew.bat issues). I didn't have time to troubleshoot it yet. So I went forward and merged the backport PR. When I created the PR I cherry-picked using the cherry-pick.sh, and assumed that it would use the same authors from the previous merge commit. However, this seems not to be the case and now I am the author with "co-author" myself. Did I have to update the co-author reference to include Solrbot? Solr 9.x is already depending on Jetty 10. (and Solr uses javax classes with > it currently). Oh, I got confused with the versions then. In that case, if Jetty 11 can be backported to branch_9x without breaking back compatibility, we may go for it. I only experimented with Jetty 12 and it wasn't compatible with hadoop-auth (and s3 module I think).
