As I learned several month ago, Kotlin 1.1 is no longer a Kotlin version that’s expected to support Java 8 language features. Do we know yet when Kotlin is expected to finally catch up?
I unfortunately just spent some time debugging some more issues that are apparently caused by the lack of Java 8 support:
MethodHandles can’t be efficiently invoked directly from Kotlin code. :\
The answer Dmitry gave here to someone having problems with
MethodHandle in Kotlin — while a very good guess as to the issue the user was experiencing — actually wasn’t the root of the problem the user was having (as is demonstrated here). The problem is this: polymorphic signature support.
Is there a new version number or time period expected for Java 8 support in Kotlin?
