Daniel Spilker resolved Bug JENKINS-19979 as Won't Fix

Sorry for any inconvenience. Usually we take compatibility very serious, but in this case something slipped through. The problem has been introduced by a refactoring in ad4c1a3 where DescriptorImpl has been moved from an inner class of ExecuteDslScripts to a top-level class.

I could not reproduce any problems when trying to update from 1.16 to 1.29 on Jenkins 1.554.2 apart from an exception that is logged while starting Jenkins:
