When working on #911 I found out about this issue: actions/checkout#435
After this I checked the Fedora build in the CI, and in the latest official version it's empty:
Luckily there is working fix, altough it's a bit ugly: https://github.com/substrait-io/substrait-java/pull/406/files#diff-15c806aa509538190832852f439e9921a23bec2da81f95ed0e4bf13c14e5b160R122-R123
Will probably send a PR to fix it (with the approach in #911), just making this ticket as a note
