java.io.UTFDataFormatException: malformed input around byte #2

Getting a nasty error when using Scala 2.12:

Project: sake-ba-source Note: Not happening when using Scala 2.11... So, this could be related to classycle and Java 8 bytecode???

Scala 2.12 probably uses invoke_dynamic stuff for lambdas etc. Classycle did not handle those constants at all!!! 😄
Of course, I made my own repo and implemented the gist of it: https://github.com/sake92/hepek-classycle Now everything works as a charm. For now, lol.
