09/17/2019, 10:01 AMIn Kotlin 1.3.30 bytecode targets for JVM versions 9, 10, 11 and 12 were added https://blog.jetbrains.com/kotlin/2019/04/kotlin-1-3-30-released/
The blog post states that
Note that so far newer versions don’t add any bytecode optimizations or features beyond the ones that exist in lower versions, but that is going to change in the future.Does this mean that the JVM itself does not have any optimizations or is it only the Kotlin generated bytecode that loses out on these optimizations for those versions?
