But I think it´s more about jGit jgit issue

Hi Benjamin, thanks for reporting.

Indeed jgitver relies on jgit for that git parsing so if worktree breaks jgit, then jgitver is also broken.

This seems to be resolved by https://github.com/jgitver/jgitver/commit/e42d69b2aa2d05bd38433f50fd00d75153380412 Could you release a new version, please?
