nit: not just @CalledByNative, but I suppose also for native methods, right?
in that case, perhaps something like:
...to qualify inner types used on JNI methods.
Must be used when an inner class is used from a class within the same package.
Example:
@JNIAdditionImport(Foo.class)
public class Bar {
  @CalledByNative
  static void doSomethingWithInner(Foo.Inner inner) {...}
}

Notes:
1) Foo must be in the same package as Bar.
2) For classes in different packages, they should be imported as:
import other.package.Foo;
and this annotation should not be used.

Done.
