Ошибка десериализации Avro — ArrayIndexOutOfBoundsException

Мой рабочий процесс — я создаю файлы avsc, генерирую классы C ++ с помощью инструмента avrogencpp и создаю двоичные закодированные данные avro в моем приложении C ++.

Я пытаюсь выяснить, почему Сценарий 2 не работает.

Сценарий 1

test.avsc

{
"namespace": "com.company.project",
"name": "Component_DeviceInfo",
"type": "record",
"doc": "Identifies a client device",
"fields": [
{
"name": "deviceId",
"type": [
"null",
"string"],
"default": null,
"doc": "Multicast Data Client Device Id. Usually unique MAC address"},
{
"name": "zoneId",
"type": [
"null",
"string"],
"default": null,
"doc": "Zone id where device belongs to"}
]
}

Кодировщик — C ++

Component_DeviceInfo deviceInfo;
deviceInfo.deviceId.set_string("device1");
deviceInfo.zoneId.set_string("zone1");
std::vector <char>tele_bytes_;
std::auto_ptr<avro::OutputStream> out = avro::memoryOutputStream(1);
avro::EncoderPtr enc = avro::binaryEncoder();
enc->init(*out);
avro::encode(*enc, deviceInfo);
out->flush();

size_t byte_count = out->byteCount();
DBG("BYTE COUNT " << byte_count);

std::auto_ptr<avro::InputStream> in = avro::memoryInputStream(*out);
avro::StreamReader reader(*in);
std::vector<uint8_t> row_data(byte_count);
reader.readBytes(&row_data[0], byte_count);

Java-декодер

@Override
public Object deserializeByteArr(Schema schema, final byte[] data){
DatumReader<GenericRecord> genericDatumReader = new SpecificDatumReader<>(schema);
Decoder decoder = DecoderFactory.get().binaryDecoder(data, null);
try {
GenericRecord userData = genericDatumReader.read(null, decoder);
System.out.println(userData);
} catch (IOException e) {
e.printStackTrace();
}
return null;
}

Сценарий 2 — не работает

Обратите внимание, что я обновил схему и восстановил файлы c ++, соответствующие схеме

Буду признателен, если кто-нибудь скажет мне, что происходит! Спасибо !
