[jira] [Updated] (AVRO-2032) Unable to decode JSON-encoded Double.NaN, Double.POSITIVE_INFINITY or Double.NEGATIVE_INFINITY

     [ https://issues.apache.org/jira/browse/AVRO-2032?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Nandor Kollar updated AVRO-2032:
--------------------------------
    Description: 
When using the JsonEncoder to serialize Double.NaN, Double.POSITIVE_INFINITY or Double.NEGATIVE_INFINITY to resulting JSON cannot be parsed by the JsonDencoder.
An AvroTypeException is thrown with the message "Expected double. Got VALUE_STRING".
When using BinaryEncoder/BinaryDecoder, it works fine.

This JUnit code snippet will reproduce the issue:
{code}
    @Test
    public void test() throws Exception {
        Schema schema = SchemaBuilder.builder()
                .record("record")
                .fields()
                    .optionalDouble("number1")
                    .optionalDouble("number2")
                    .optionalDouble("number3")
                .endRecord();
        GenericData.Record record = new GenericData.Record(schema);
        record.put("number1", Double.NaN);
        record.put("number2", Double.POSITIVE_INFINITY);
        record.put("number3", Double.NEGATIVE_INFINITY);

        ByteArrayOutputStream out = new ByteArrayOutputStream();
        JsonEncoder encoder = EncoderFactory.get().jsonEncoder(schema, out);
        new GenericDatumWriter<GenericRecord>(schema).write(record, encoder);
        encoder.flush();
        System.out.println(out);

        Decoder decoder = DecoderFactory.get().jsonDecoder(schema, out.toString());
        GenericData.Record deserialized = new GenericData.Record(schema);
        new GenericDatumReader<GenericRecord>(schema).read(deserialized, decoder);
    }
{code}
