PI94390: DFHPI1007 UNEXPECTED_ELEMENT WHEN USING NATIVE JSON PARSER TO PARSE JSON THAT HAS AN EMPTY OBJECT AND ANOTHER ELEMENT

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• DFHPI1007 UNEXPECTED_ELEMENT error when using the native
  (non-Java) JSON parser to process JSON which contains an empty
  object followed by another element.
  For example:
  {
   "a": {},
    "b": "c"
  }
  If the empty object, "a" in the example above", is omitted (or
  contains a value) then the JSON is parsed correctly. The
  DFHPI1007 error will reference the next element, "b" in this
  case.
  The problem is that when an empty JSON object is parsed, then
  the close right brace "}" causes the parser to think that the
  object in question has been processed and so has the object it
  is within.  As a result the parser is now out of sync with the
  JSON it is processing causing the next element to be rejected.

  ****************************************************************
  * PROBLEM DESCRIPTION: Native JSON parser failed because of    *
  *                      incorrect input (UNDEFINED_ELEMENT *).  *
  *                      Message DFHPI1007 transformation failed *
  *                      occurs.                                 *
  ****************************************************************
  The native JSON parser is used to convert JSON data to
  application data. A JSON schema declares an object followed by
  other elements. If this object is empty, json_close_element will
  be executed twice continuously. That cause the parser think it
  has seen the end of JSON data which will leave the parsing loop,
  and all the remaining data are not parsed. Then message
  DFHPI1007 transformation failed occurs.

• DFHJUPAR has been changed to parse empty object correctly.
