Hi all, just reported a NPE problem: https://issues.apache.org/jira/browse/CALCITE-1054
I would like to understand the problem at hand better, but I could use some pointers how to go forward: - which unit tests would be good candidates to cover this problem? - where could I find documentation on Calcite's code generation? Advice on all loosely related matters is very welcome. Thank you! Frankie
