      Description

      Hi,

        We are trying to update root in CMSSW Special IBs (which use root v6-14-00-patches and master branch) and we noticed that some unit tests and release validation tests failed with following error. Any idea what changed in root v6-14-00-patches branch between commit 5bb362b and d029b6f which could have caused this problem?

      Thanks, --Shahzad
