Bug or Feature Request: How to serialize int array?

Description: I have a column that is of type int[]:

@Table(name = "Notes", database = AppDatabase.class)
public class Note extends Model {
    @PrimaryKey
    private Long id;
    @Column(name = "title")
    private String title;
    @Column(name = "text")
    private String text;
    @Column(name = "color")
    private int color;
    @Column(name = "numbers")
    private int[] numbers;
}

I want to serialize it as String (e.g. "[1,2,3]") so I made an IntArraySerializer:

public class IntArraySerializer extends TypeSerializer<int[], String> {
    @Nullable
    @Override
    public String serialize(@Nullable int[] data) {
        if (data == null) return null;

        return new Gson().toJson(data);
    }

    @Nullable
    @Override
    public int[] deserialize(@Nullable String data) {
        if (data == null) return null;

        return new Gson().fromJson(data, int[].class);
    }
}

But when I call ReActiveAndroid.init()

        DatabaseConfig appDatabaseConfig = new DatabaseConfig.Builder(AppDatabase.class)
                .addModelClasses(Note.class, Folder.class, NoteFolderRelation.class)
                .addTypeSerializers(IntArraySerializer.class)
                .disableMigrationsChecking()
                .build();

        ReActiveAndroid.init(new ReActiveConfig.Builder(this)
                .addDatabaseConfigs(appDatabaseConfig)
                .build());

app crashes with following error:

P.S. This worked in https://github.com/pardom-zz/ActiveAndroid

I also tried with String[] array and get the same error.

Did you find a solution?
