BasicDBObject/Document toString methods throw exceptions when one of the fields is a UUID

XMLWordPrintableJSON

    • Type: Icon: Bug Bug
    • Resolution: Fixed
    • Priority: Icon: Major - P3 Major - P3
    • 4.3.0
    • Affects Version/s: 4.0.0
    • Component/s: BSON
    • Minor Change
    • Not Needed

      Consider this code:

            var uuid = UUID.randomUUID()
      var dbo1 = new BasicDBObject("_id", uuid);
 
      dbo1.toString()

      In the 3.x driver this will print the dbo, but in 4.x it will throw:

      Exception in thread "main" org.bson.codecs.configuration.CodecConfigurationException: 
The uuidRepresentation has not been specified, so the UUID cannot be encoded.
	at org.bson.codecs.UuidCodec.encode(UuidCodec.java:72)
	at org.bson.codecs.UuidCodec.encode(UuidCodec.java:37)
	at org.bson.codecs.EncoderContext.encodeWithChildContext(EncoderContext.java:91)

	at com.mongodb.BasicDBObject.toBson(BasicDBObject.java:225)
	at com.mongodb.BasicDBObject.equals(BasicDBObject.java:21

      This is a breaking change. There are workarounds, first rendering toJson with a specific encoder or creating the bson with a UUID representation, but still tricky.

      Would be great if toString and toJson could work right out of the box.
