Hello! I have issue with compiling YandexMapKit inside kotlin project:
```
:app:compileDebugKotlinAfterJava
Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
    class ru.yandex.yandexmapkit.MapController, unresolved supertypes: StartupListener
```
The code of following class(from jar):
```
public interface StartupController$StartupListener {
    void onStartup(bs var1);
}
```
Is it problem of library, or of kotlin? Will character `$` in name of public java class make problem for kotlin compiler?
