Github user fhueske commented on the issue: https://github.com/apache/flink/pull/3880 Hi @Xpray, I left a comment on the related JIRA issue. In short, I do not why we should remove methods with constant signature and call them via reflection. This makes the code more prone for failures, it is less comfortable for users that need to override the methods and does not change anything for users that do not need these methods. It would be great if you could reply on the JIRA. Thank you, Fabian
