PH10391: DFHPI1007 ISSUED WITH UNDEFINED_ELEMENT WHEN A NESTING LEVEL WITHIN BRACKETS INCLUDES AN EMPTY OBJECT

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• You are parsing a JSON message that includes an array with
  several levels of nested brackets, both square and curly.  This
  message was successfully parsed at CICS TS 5.1, but not at CICS
  TS 5.4.  You receive message:
  
  DFHPI1007 YOURCICS TRAN 01234 JSON to data
  transformation failed because of incorrect input
  (UNDEFINED_ELEMENT YourElement) for JSONTRANSFRM YourResource.
  
  CICS correctly identifies the start of the array of nested
  objects, but when the first object encountered is empty, the
  closing bracket is interpreted as the end of the entire array,
  leading to the the parser losing syncronization with the entire
  structure.
  
  
  Additional Symptom(s) Search Keyword(s): KIXREVPAD
  

Local fix

• Switch to using the JVM server based JSON parsing logic that
  was used in CICS TS 5.1.

  * PROBLEM DESCRIPTION: Native JSON parser failed because of    *
  *                      incorrect input (UNDEFINED_ELEMENT X).  *
  *                      Message DFHPI1007 transformation failed *
  *                      occurs.                                 *
  ****************************************************************
  The native JSON parser is used to convert JSON data to
  application data. A JSON schema declares a required array of
  objects. If one of the objects in the array is empty the parser
  thinks it is at the end of the array causing the remaining JSON
  data to be parsed incorrectly.  This will most likely lead to
  message DFHPI1007 with insert UNDEFINED_ELEMENT being issued.

Problem conclusion

• DFHPIJP1 has been changed to parse empty objects in an array
  correctly.
