When I configure a job to use a branch in the form feature/myfeature (as would be created by git-flow when starting a feature branch) the checkout in the workspace ends up being from the master branch after the job runs. The feature/myfeature branch is present on the git server pointed to by the URL configured in the job and can be successfully checked out into the workspace manually using the configured credentials. Further, configuring other simple branch names, like develop, as the branch in the job configuration works fully as expected – only branch names beginning with 'feature/' seem to encounter a problem.
