Pieter Dekinder created AVRO-2032:
-------------------------------------
Summary: Unable to decode JSON-encoded Double.NaN,
Double.POSITIVE_INFINITY or Double.NEGATIVE_INFINITY
Key: AVRO-2032
URL: https://issues.apache.org/jira/browse/AVRO-2032
Project: Avro
Issue Type: Bug
Components: java
Affects Versions: 1.8.1
Reporter: Pieter Dekinder
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:
@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);
}
