APAR status

• Closed as program error.

Error description

• Previously empty JSON arrays may not have been present in the
  JSON produced by CICS if the corresponding element in the
  language structure was empty.
  .
  PI67641/UI43347 altered the behavior without providing a proper
  mechanism to control the handling of empty JSON arrays. Clients
  testing for the presence or absence of a JSON array must now
  test for an empty or populated JSON array.
  .
  Need an option for omitting empty optional arrays.  The JS2LS
  utility needs to honor the omission of the "required"
  validation keyword in the JSON schema for JSON arrays. If the
  array is empty and not required as specified in the JSON
  schema, do not include the array in the JSON object. If the
  array is empty and is required as specified in the JSON schema,
  include an empty array in the JSON
  

Local fix

• The application receiving the JSON would need to ignore the
  values if they are not needed because thy contain no values.
  

Problem summary

• DFHJS2LS does not provide mechanism to control empty JSON arrays
  

Problem conclusion

• DFHJS2LS has been corrected so that "is optional array" would be
   supported.
  
  The problem listed in this APAR has been resolved with
  IBM Rational Developer for z Systems V9.5.1.6 Fix Pack which
