Remove LambdaForm$Hidden annotation from emitted code by Yarikx · Pull Request #118 · luontola/retrolambda
@Yarikx, @simophin I have also run into this issue on Android 4.1 and 4.2. Your PR worked wonderfully!
For anyone else who runs into this issue, as this has yet to be merged, I suggest building your own JAR using this branch. I compiled the JAR using the docker container without any issues (follow the instructions here).
If you are using the Retrolambda Gradle plugin, follow the instructions found here to use the local JAR instead.
