As current maintainer (who's seeking co-maintainers
https://groups.google.com/g/jenkinsci-dev/c/WtNZKVWVlJ0/m/Zbd7SH_GFAAJ) I'd be happy to review a fix and release it, but won't be able to undertake the change.
Regarding adoption /co-maintaining, I'd be happy for you to get involved, as I'm currently not able to balance this (which I unfortunately no longer use for work, nor do I do much JVM stuff in recent years) but note that there's a long backlog of fixes and enhancements raised by the community.
I'd got through a few of them when I started maintaining, but there's still quite a few things to do.
Don't mean to put you off, just want to make sure you're aware going into it!
