Probably I've forgotten to run `clean`.
The method `iterate$default$3` is a method which automatically created by
Scala for calculation of default value for parameter `keepPartitioning`. I
tried different ways to exclude it but it didn't help. Anyway it should be
somehow tracked by japicmp so I created the issue there
