BasicDBObject.parse fails to parse json if it contains big numbers

XMLWordPrintableJSON

    • Type: Icon: Bug Bug
    • Resolution: Works as Designed
    • Priority: Icon: Minor - P4 Minor - P4
    • None
    • Affects Version/s: 3.4.3, 3.6.0
    • Component/s: JSON
    • Labels:
      None

      Input:
      JSON with big number (exceeds java.lang.Long limits).
      Sample code:

      BasicDBObject obj = BasicDBObject.parse("{\"bigNum\": 11111111111111111111111}");
System.out.println(obj);

      Expected behavior:
      BasicDBObject.parse handles such number as Decimal128 (added in 3.4)

      Actual behavior:
      BasicDBObject.parse fails with NumberFormatException. (JsonScanner.scanNumber tries to parse number as Integer, Long or Double, but not Decimal128).

      Exception in thread "main" java.lang.NumberFormatException: For input string: "11111111111111111111111"
