Graal Native Image - Substitutions

I am currently trying to build a project with graal vm native image plugin and am getting the following error

I have posted an issue with them but perhaps it is something you can help me with it would really help. The issue I have posted is oracle/graal#1603 with tink 1.3.0 rc1

It seems that this issue is due to netty-substitutions in protobuf code (rather than Tink), and maybe can be fixed as described in oracle/graal#917 and https://medium.com/graalvm/instant-netty-startup-using-graalvm-native-image-generation-ed6f14ff7692
Please give it a try and let us know whether it worked.

Sorry I have edited this message as I you were correct it was a substitution I was missing. I compared against this oracle/graal#917 and added

@TargetClass(className = "com.google.protobuf.UnsafeUtil")
final class Target_com_google_protobuf_UnsafeUtil {
    @Substitute
    static sun.misc.Unsafe getUnsafe() {
        return null;
    }
}

and it is working. Thank you very much for your help.
