Creating an orphan branch is about building a commit with no parents, and then setting some branch to point to that commit. The latter can be done easily with any RefUpdate command, either create a new branch, or force update an existing branch to the new commit's ObjectId. Creating a new commit with no parents probably requires using the CommitBuilder class directly. The CommitCommand only supports HEAD and creates a new commit on top of that. You may be able to relink HEAD to a non-existant branch name, then run CommitCommand to make an orphan branch.
