Github user paulk-asert commented on the pull request: https://github.com/apache/groovy/commit/1bcaaeaf60078dd5a9aca5cbf1df8f45de68db60#commitcomment-28387349 Not all the classes probably gave errors but yep, that will probably be the easiest. The only other comment I'll make is that even for the ObservableList/Set/Map case, neither the value report by japicmp or generated by Intellij gave the right results. I had to be by what the serialize/deserialize rout-trip test gave. Perhaps I needed to clear out IntelliJ's classes directory between switching branches - not sure what was going wrong.
