Can auto-value-parcel-adapter cope with Typed Set of another auto-value Class?

I am investigating auto-value and its extensions, namely auto-value-parcel and auto-value-parcel-adapter within my Android application.

I have these model classes:-

@AutoValue
public abstract class Xenarchaeota implements Parcelable {

    @ParcelAdapter(AmoebaTypeAdapter.class)
    public abstract Set<Amoeba> amoebas();

    public static Builder builder() {
        return new AutoValue_Xenarchaeota.Builder();
    }

    @AutoValue.Builder
    public abstract static class Builder {

        public abstract Builder setAmoebas(Set<Amoeba> value);

        public abstract Xenarchaeota build();
    }
}

and

@AutoValue
public abstract class Amoeba implements Parcelable {

    public abstract String surname();

    public static Builder builder() {
        return new AutoValue_Amoeba.Builder();
    }

    @AutoValue.Builder
    public abstract static class Builder {

        public abstract Builder surname(final String value);

        public abstract Amoeba build();
    }

}

My type adapter is where my issues arise

class AmoebaTypeAdapter implements TypeAdapter<Set<Amoeba>> {

    @Override
    public Set<Amoeba> fromParcel(Parcel in) {
        final ArrayList<Amoeba> arrayList = new ArrayList<>();
        in.readTypedList(arrayList, Amoeba.CREATOR); // How to access the CREATOR?
        return new TreeSet<>(arrayList);
    }

    @Override
    public void toParcel(Set<Amoeba> value, Parcel dest) {
        final ArrayList<Amoeba> arrayList = new ArrayList<>(value);
        dest.writeTypedList(arrayList);
    }
}

The CREATOR I need to pass to the readTypedArray is declared in AutoValue_Amoeba.

Where is my mistake? misunderstanding of auto-value-parcel?

AutoValue: Parcel extension can't handle sets, but if you convert the property to a List things will work out of the box without a custom adapter. If you want to treat it as a Set you could do this. Keep in mind you'll probably also want to cache the Set.

@AutoValue
public abstract class Xenarchaeota implements Parcelable {

    abstract List<Amoeba> amoebaList();
    public Set<Amoeba> amoebas() {
        return new TreeSet(amoebaList());
    }

    public static Builder builder() {
        return new AutoValue_Xenarchaeota.Builder();
    }

    @AutoValue.Builder
    public abstract static class Builder {

        public abstract Builder setAmoebas(Set<Amoeba> value);

        public abstract Xenarchaeota build();
    }
}
