IV68382: COM/IBM/DATAACCESS/DECIMALDATA.CONVERTINTEGERTOEXTERNALDECIMAL R ETURNS INCORRECT RESULTS

APAR status

• Closed as program error.

Error description

• Error Message: N/A
  .
  Stack Trace: N/A
  .
  Methods
  com/ibm/dataaccess/DecimalData.convertIntegerToExternalDecimal,
  com/ibm/dataaccess/DecimalData.convertLongToExternalDecimal,
  com/ibm/dataaccess/DecimalData.convertExternalDecimalToInteger,
  com/ibm/dataaccess/DecimalData.convertExternalDecimalToLong may
  return incorrect results in situations where there are multiple
  such calls in a single block.
  

Local fix

• This issue can be worked around using the
  -Xjit:disableIntrinsics option. Note however that this option
  will disable JIT acceleration of the DAA library, thus having a
  negative performance impact.
  

Problem summary

• The problem is caused by an optimization pass that introduces
  incorrect commoning of results from multiple DAA method calls.
  

Problem conclusion

• The JIT has been updated to prevent commoning of the results of
  multiple DAA method calls.
