APAR status

  • Closed as program error.

Error description

  • Error Message: Method
    com/ibm/dataaccess/DecimalData.convertPackedDecimalToLong does
    not throw an exception when invoked with parameters that should
    otherwise generate an exception.
    .
    Stack Trace: N/A
    .
    The problem is only seen when multiple calls to
    com/ibm/dataaccess/DecimalData.convertPackedDecimalToLong are
    present within the same scope block and there is no control flow
    between them.
    

Local fix

  • This issue can be worked around using the
    -Xjit:disableVariablePrecisionDAA option. Note that the addition
    of this option may affect performance.
    

Problem summary

  • When multiple calls to the described method are present, in
    certain situations the optimizer may re-use the values from the
    previous call if they share the same parameters. In some cases
    the optimizer makes an incorrect transformation, thus passing
    incorrect parameters to the method call.
    

Problem conclusion

  • The JIT optimizer has been updated to prevent the faulty
    transformations.
