Thank you Alexandre, it worked like a charm with both the ways suggested (annotated dummy class or reflection-config.json file). Never thought I had to explicitly declare for reflection a pretty old (and possibly obsolete) class like java.util.Date. But as I said in my question java.util.Date and java.time.Instant are the only types available in protostream schema for time objects. And honestly Instant is definitely meaningless for informations without seconds like starting or ending validity dates Anyway it did the trick, you made my day! Cheers mate
