kotlinlang

Hi, my library can be used in kotlin &amp; java, I created an interface with several method they have default impl, but When I implements it im java, IDEA suggest me implements all the method, I added the compiler args `-Xjvm-default=all-compatibility`  or `-Xjvm-default=all` and sync the project but the compiler reported a warning says `Flag is not supported by this version of the compiler: -Xjvm-default=all-compatibility` . I enabled K2 in the Intellij IDEA
