PI79210: CICS JSON TRANSFORM PRODUCING ADDITIONAL COMMAS 17/06/20 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Recently upgraded our CICS to TS 5.3.  We have CICS services
  that have started to produce invalid JSON as a result of the
  upgrade.
  
  The web service is using the CICS transform to generate the JSON
  response and we are finding many double commas being generated
  which is invalid JSON. The CICS verb itself does not fail, but
  it does produce an invalid JSON.
  
  This problem is due to an additional comma is output ahead
  of an empty array.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users with UI43343 applied.         *
  ****************************************************************
  * PROBLEM DESCRIPTION: Native JSON generator produces JSON     *
  *                      with two commas ahead of an empty       *
  *                      array.                                  *
  ****************************************************************
  The native (non-Java) JSON generator is used to convert
  application data to JSON.  In this particular case, the
  application data contains a structure that is converted to an
  empty JSON array.  Residual state causes two commas to be placed
  between the proceeding name/value pair and the empty array in
  the JSON produced, making the JSON invalid.
  

Problem conclusion

• UI43343
  
  DFHPIJG has been modified to ensure empty JSON arrays are
  proceeded by a single comma if the array is following another
  name/value pair at the same nesting level.
