@Contract("null, null, null, !null -> fail")
private static void loadArguments(GeneratorAdapter ga, Type[] interfaceTypes, Type[] targetTypes, boolean isTargetPublic) {
    Ensure.ensureCondition(interfaceTypes.length == targetTypes.length,
            "Interface and target parameter count don't match!");

    for(int i = 0; i < interfaceTypes.length; i++) {
        Type interfaceType = interfaceTypes[i];
        Type targetType = targetTypes[i];

        ga.loadArg(i);

        /* Do not do boxing/unboxing if MethodHandle.invoke is used, it handles them on its own */
