The code is checking if the argument class is a superclass of LifecycleOwner instead of if LifecycleOwner being a superclass of the argument class.

class ClassesInfoCache {
    ...
    private CallbackInfo createInfo(Class klass, @Nullable Method[] declaredMethods) {
        ...
        for (Method method : methods) {
            OnLifecycleEvent annotation = method.getAnnotation(OnLifecycleEvent.class);
            if (annotation == null) {
                continue;
            }
            hasLifecycleMethods = true;
            Class<?>[] params = method.getParameterTypes();
            int callType = CALL_TYPE_NO_ARG;
            if (params.length > 0) {
                callType = CALL_TYPE_PROVIDER;

                /***
                * This is where the issue is found. We want to verify the argument class inherits from LifecycleOwner instead
                ***/

                if (!params[0].isAssignableFrom(LifecycleOwner.class)) {
                    throw new IllegalArgumentException(
                            "invalid parameter type. Must be one and instanceof LifecycleOwner");
                }
            }
