[jgit-dev] Retrieving parent branch name

[Alaa Nassef <alan.125@xxxxxxxxx>]

I'm working on a project where I create a bare repository from a remote one, and fetch only one branch. What I'm trying to find out now is the name of the parent branch (or more specifically, the commit on the parent branch where this branch was created from) to identify the commits that were done on this branch only. For example, if my repository has a RefSpec for branch featureA only, and this was created from branch development on remote from commit 123, what can I do to find out this info?
