This commit broke backward compatibility https://github.com/jenkinsci/jenkins/commit/bdaf5eadc276804e249fdcdebed110cf6329d0f6
It causes problem with loading matrix configuration with & - it does not find the folder with configuration and it creates new one. (so there is folder linux&&ipv6 and folder linux%26%26ipv6) Revert commit or any other idea how to do configuration loading resistant to changes like that? Thanks
