You offered very little information but my guess is that you are targeting JVM 17 and Kotlin is producing Java 17 bytecode. R8 added support for Java 17 in newer versions, it's not really a keeper issue. Just update your R8 version (there are instructions in the site docs). Next release will also raise the default version.

In the future, please do include more information. I only recognized this because I'd happened to have seen the error before.

Thanks for the info. Only open issue about this is regarding JDK 21, so I assumed 17 was already supported, since it's much older than 17: #129
