PH18370: STORAGE VIOLATION WHILE PROCESSING A JSON PIPELINE REQUEST

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• A storage violation DFHSM0102 occurs when using the native
  (non-Java) JSON parser.  Parsing completes successfully, but
  when an area of heap storage allocated by DFHPIJP1 is freed
  Storage Manager domain detects that the trailing crumple zone
  has been overridden with zeros.
  
  This problem occurs when the JSON parser needs to populate a
  container with a repeating structure but that repeating
  structure is empty.  A copy of zeros is performed in a buffer
  unnecessarily and if close to the end of the current heap
  segment it can overrun into the crumple zone.

  *                      X'420B') has been detected by module    *
  *                      DFHS2GF.                                *
  ****************************************************************
  The native (non-Java) JSON parser processes input JSON that
  contains an empty array. A defect in DFHPIJP1 means that a heap
  segment can be overrun which causes a storage violation to be
  detected at the end of processing and message DFHSM0102 to be
  issued.
  

Problem conclusion

• DFHPIJP1 has been changed to ensure that the storage violation
  does not occur.
