Is there a (public) project where this issue can be reproduced? (optional)

No response

Your Environment (optional)

No response

Context (optional)

The cause seems to be within jgit which does not set the initialBranch when initializing a repository when cloning. A workaround is to modify .gitconfig defaultBranch, or change master in the test to the value of defaultBranch. There is probably a way to fix the test to not rely on the value of initialBranch.
