PI64780: JSON TO DATA TRANSFORMATION FAILED. A CONVERSION ERROR (OUTPUT_OVERFLOW) OCCURRED 16/12/05 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• JSON script is getting JSON to data transformation failed. A
  conversion error (OUTPUT_OVERFLOW) occurred. In the trace of
  the dump that shows the error, it shows a DFHPI1009
  Transformation Exception occurring in one of the methods. The
  field/variable that is being worked with is numerical.
  
  This problem occurs if the JSON value is in one of the
  following forms:
  
   - 0.n
   - .n
   - "0.n"
  
  If the input is ".n" (with quotes) then this works.
  
  The DFHJS2LS assistant is determining that there will never be
  a significant (non-zero) digit before the decimal point.
  However, we shouldn't be rejecting inputs with a zero before
  the decimal point at runtime.

  ****************************************************************
  DFHJS2LS has been used to create a JSON web service, or
  so that the DFHJSON linkable interface can be used.  The
  schema provided declared a decimal which should never have a
  non-zero digit before the decimal point.  For example:
  
  "fieldA": {
    "type":"number",
    "format":"decimal",
    "maximum":0.99,
    "minimum":-0.99
  }
  
  JSON is supplied to CICS at runtime which contains a value
  for this decimal in one of the following forms:
  
  0.n
  .n
  "0.n"
  
  CICS incorrectly expects no digits to be specified before
  the decimal point, but finds one, causing a DFHPI1009
  message to be issued with a conversion error of
  OUTPUT_OVERFLOW.

Problem conclusion

• ConversionLib.java has been modified to tolerate a 0 digit
  before the decimal point in the scenario described above.
