APAR status

• Closed as program error.

Error description

• z/OS Connect does not preserve json payload element ordering
  as
  shown in copybook files. More precisely, if the copybook
  file
  has entries a,b,c,d, in order, z/OS Connect does not keep
  the order of the elements when the payload is processed and
  sent to its destination. For example: the order might be
  c,d,a,b

Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server Liberty Profile for z/OS using z/OS  *
  *                  Connect.                                    *
  ****************************************************************
  * PROBLEM DESCRIPTION: z/OS Connect alters the order of        *
  *                      entries in JSON payload objects         *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  During a z/OS Connect service invocation process, the order of
  elements in JSON objects within the request request payloads are
  altered. For example:
  
  If a service endpoint returns the following json object :
  {"e":"f", "c":"d", "a";"b"}
  The client may see the following json object: {"a":"b", "c":"d",
  "e";"f"}
  
  Note that the payload content is not affected. It is only
  ordering of elements in a JSON object that is altered.
  

Problem conclusion

• An attribute definition with the name of
  preserveJsonObjectPayloadOrder was added. This attribute can be
  set under the zosConnectManager element and it will apply to all
  configured services. When set to true, z/OS Connect does not
  alter the ordering of JSON objects' entries that are contained
  in the payloads.
  
  The fix for this APAR is currently targeted for inclusion in fix
  pack 8.5.5.9.  Please refer to the Recommended Updates page for
