How to encode/decode java.util.Properties

[Stefan Schönig]

I'm not able to Encode/Decode a class from the Standard-JDK ( 
java.util.Properties).
The inserted key/value pair is not available after decode.
Any idea what goint wrong?!?
Thank in advance!


Code of the application:

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.util.Properties;

import org.apache.avro.*;
import org.apache.avro.io.*;
import org.apache.avro.reflect.*;

public class AvroPropertiesTest {

        public static void main(String[] args) throws IOException {
                ReflectData reflectData = ReflectData.get();
                Schema schema = reflectData.getSchema(Properties.class);
                
                ByteArrayOutputStream os = new ByteArrayOutputStream();
                Encoder e = EncoderFactory.get().binaryEncoder(os, null);

                Properties properties = new Properties();
                properties.put("Hello", "World");

                System.out.println("properties: " + properties);
                
                DatumWriter<Properties> writer =
                        new ReflectDatumWriter<Properties>(schema);
                writer.write(properties, e);
                e.flush();

		ReflectDatumReader<Properties> reader = new 
ReflectDatumReader<Properties>(
                                schema);
                Decoder decoder = 
DecoderFactory.get().binaryDecoder(os.toByteArray(),
                                null);
                Properties decodedProperties = (Properties) reader.read(null, 
decoder);

                System.out.println("decodedProperties: " + decodedProperties);
        }
}
