<@U092308M7>: I have been debugging my issue related to lambda being `final` in Kotlin by default, and in fact that may be « just » a low level bytecode difference (compared to Java) that causes our problem since if I create a final implementation class of functional interfaces in Java we have no issue at all. I have been debugging that and found that in Java, `Method.invoke()` works on `public final` implementation of functional interfaces because the `Method#override` field is `true` (see <http://grepcode.com/file/repository.grepcode.com/java/root/jdk/openjdk/8u40-b25/java/lang/reflect/Method.java?av=f#482> with `override` to `true` there is no access check), while in Kotlin it is `false`. Could I raise an issue with a repro project (with both Java and Kotlin code) to see if there is something to fix on Kotlin side?
