Matěj Novotný updated FLINK-12303:
----------------------------------
Description:
When you use lambdas inside event classes used in streams it does work in Scala
2.11. It stoped working in Scala 2.12. It does compile but does not process any
data and does not throw any exception. I would expect that it would not compile
in case I have used some not supported field in event class.
For more detail check my demonstration repo, please:

When you use lambdas inside event classes used in streams it does work in Scala

data and does not throw any exception. I don't think that Flink should support
lambdas inside event classes processed in streams but I think that It should
not behave like this. I would expect that it will not compile in case I have
used some not supported field in event class.
