Hi,
is there effort to update the default jdk at some point? I could help with
it. I'm not familiar with the guix java build systems, but have long
experience as a Java developer. I also maintain few java packages in Fedora
and saw the transition to to jdk11 [1], jdk17 [2] and now to jdk21 [3]. The
pages have documented common issues and workarounds, which might help.

Best wishes,
Markku
