Error using auto-value-defensive-copy with auto-value-gson

[hugonardo]

I have an @AutoValue class that uses Gson's @SerializedName annotation in a Android Project.

On method annotated with @DefensiveCopy and @SerializedName, an error happens in generated class, where @SerializedName's value is not copied.

Follows the code:

@AutoValue
public abstract class UserResponse {

    public static TypeAdapter<UserResponse> typeAdapter(Gson gson) {
        return new AutoValue_UserResponse.GsonTypeAdapter(gson);
    }

    @SerializedName("cod_usuario")
    public abstract String codUsuario();

    @Nullable
    @SerializedName("codigo_motorista")
    public abstract String codMotorista();

    @SerializedName("codigo_veiculo")
    public abstract String codVeiculo();

    @SerializedName("nome_usuario")
    public abstract String nomeDoUsuario();

    @DefensiveCopy
    @SerializedName("grupos")
    public abstract List<String> grupos();
}

---

abstract class $AutoValue_UserResponse extends $$AutoValue_UserResponse {
  $AutoValue_UserResponse(String codUsuario, @Nullable String codMotorista, String codVeiculo,
      String nomeDoUsuario, List<String> grupos) {
    super(codUsuario, codMotorista, codVeiculo, nomeDoUsuario, grupos);
  }

  @DefensiveCopy
  @SerializedName // <- Here the error. The value "groups" is not copied.
  @Override
  public List<String> grupos() {
    return java.util.Collections.unmodifiableList(super.grupos());
  }
}
