APAR status

  • Closed as program error.

Error description

  • Error Message: N/A
    .
    Stack Trace: N/A
    .
    

Local fix

  • A workaround is to disable to use -Xnodfpbd.  There might be an
    impact to BigDecimal performance with this option.
    

Problem summary

  • The Java virtual machine (JVM) incorrectly calls a private stub
    routine for java/math/BigDecimal.DFPBCDDigits, used within
    certain DFP related paths of BigDecimal.toString, instead of
    generating the corresponding convert instruction to packed
    decimal.   This problem is exposed only on 31-bit zLinux JVMs,
    or 31-bit zOS JVMs on z10 architecture.
    

Problem conclusion

  • This defect will be fixed in:
    6.0.1 SR2
    7.0.0 SR1
    .
    The JVM has been updated to generate the proper convert
    instruction for java/math/BigDecimal.DFPBCDDigits on the
    affected platforms.
