> I installed avro 1.8.2 on my ubuntu build machine and generated test.h using avrogencpp
tool. 
> Then, I created binary encoded avro data as follows:
> {code:c++}
>     MyDevice device;
>     device.deviceId.set_string("device1");
>     Event event;
>     event.myDevice.set_MyDevice(device);
>     std::vector<char> bytes;
>     std::auto_ptr<avro::OutputStream> out = avro::memoryOutputStream(1);
>     avro::EncoderPtr e = avro::binaryEncoder();
>     e->init(*out);
>     avro::encode(*e, event);
>     out->flush();
> {code}
> I deserialize my data in Java application as follows:
> {code:java}
> Schema schema = SchemaUtils.getSchemaFromFile("src/main/resources/schemas/test.avsc");
> DatumReader<GenericRecord> genericDatumReader = new GenericDatumReader<>(schema);
>         Decoder decoder = DecoderFactory.get().binaryDecoder(data, null);
>         try {
>             GenericRecord userData = genericDatumReader.read(null, decoder);
>             System.out.println(userData);
>         } catch (IOException e) {
>             e.printStackTrace();
>         }
> {code}
> And the result is 
> {noformat}
> java.lang.ArrayIndexOutOfBoundsException: 7
