It should be using the target repository, but instead it's using the "fork" (which is the repo from which we create the pull request if /backport is successful).

The dependent pull request has now been integrated, and the target branch of this pull request has been updated. This means that changes from the dependent pull request can start to show up as belonging to this pull request, which may be confusing for reviewers. To remedy this situation, simply merge the latest changes from the new target branch into this pull request by running commands similar to these in the local repository for your personal fork:


git checkout backport-cleanup
git fetch https://git.openjdk.java.net/skara master
git merge FETCH_HEAD
# if there are conflicts, follow the instructions given by git merge
git commit -m "Merge master"
git push
