IT27270: JSON PARSER ACCEPTS OBJECTS WITH DUPLICATE KEYS

APAR status

• Closed as program error.

Error description

• The JSON parser and serializer will accept objects that have
  multiple keys with the same name. JSON objects with duplicate
  keys are invalid and a ParserException should be thrown during
  an attempt to parse or serialize invalid objects of this type.
  

Local fix

• n/a
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of IBM Integration Bus version 10 and App Connect
  Enterprise version 11 using the JSON parser
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  When parsing or serialising using the JSON parser duplicate keys
  are permitted in both objects and arrays. This does not conform
  to the JSON specification.
  

Problem conclusion

• This APAR introduces a new property "objectStructure" on the
  ComIbmJSONParserFactory Resource Manager. When set to the value
  "strict" this will cause the parser to emit a BIP5734 error when
  parsing objects or arrays with duplicate keys or a BIP5733 error
  when serializing trees that would result in a JSON object that
  has an array or object with duplicate keys.
  
  In Integration Bus Version 10 this new property can be set using
  mqsichangeproperties, on App Copnnect v11 the property can be
  customised in the server.conf.yaml files.
