      Description

      We use feature branches on a git repository running on a GitLab server; with a webhook to poll jenkins on the git repository. We've several branches:
      master
      develop
      feature/A
      feature/B
      ...
      A user from doc team added some feature branches named with a capital letter:
      Feature/C
      Feature/D
      ...
      From this point, our job configured to build our application on feature branches commit detection with pattern */feature/${FEATURE_BRANCH} always built the same branch feature/A even if changes were made in feature/B etc.

      I reproduced the problem on a fresh git repository, reproducing a quick life of the repository; before the addition of Feature/C; everything ran fine. With the Addition of Feature/C; the problem occurred.

      When both feature and Feature branches were present; the polling was triggered by GitLab but the detection of the origin branch of the commit does not work on jenkins.

      I found as workaround to change my pattern from */feature/${FEATURE_BRANCH} to */*eature/${FEATURE_BRANCH} but I was expecting that even if feature branches were added starting with Feature instead of feature; the process would detect and get the commit on the right branch.

      Some logs:

      Example of bad detection (last commit was not on the feature/sync branch):
