      On reading UUID subtype V4 from MongoDB using mongo-java-driver 3.12.5, BsonBinary subtype v4 (STANDARD Uuid) gets converted back to Binary and not UUID.

      Line of code where this bug occurs:
      https://github.com/mongodb/mongo-java-driver/blob/master/bson/src/main/org/bson/BSONCallbackAdapter.java#L86

      Which throws mapping exception only in case of UUID v4 (and not in V3) : Causing: dev.morphia.mapping.MappingException: Could not map Entity with ID: org.bson.types.Binary@e1123829

      As a result, calling client is forced to add a decoding hook transformer for Binary to UUID
