Krzysztof Chmielewski commented on FLINK-31021: ----------------------------------------------- Ok so I verified and it seems that this is NOT a regression caused by my recent change to Code Splitter. It seems that splitting static methods was never supported. I've checked on 1.15 branch. I think that the question we should ask here is this in fact a bug and do we need to make Code Splitter to handle Static methods? Quating [~TsReaper] from https://github.com/apache/flink/pull/21393#pullrequestreview-1273870828 {code:java} Our code splitter is not a universal solution. It only works for Flink generated code under several restrictions. {code} [~xccui] is there any Flink SQL query that makes Planner to generate Java code with static methods? If so, could you provide one? If in fact this is needed feature I can work on it since recently I've made bigger changes to code splitter and I would be fairly easy for me to add this.
