APAR status

  • Closed as program error.

Error description

  • Error Message: N/A.  Errors will only be reported if the
    application happens to be self-testing;
    otherwise the symptom will just be corruption of numerical data.
    .
    Stack Trace: N/A
    .
    Does NOT occur in Java 5 or Java 6.  Only Java 7 has this
    problem.
    On System Z, this only occurs on z9 or newer.
    On POWER, this only occurs on POWER6 or newer.
    

Local fix

Problem summary

  • BigDecimal contains some method that the jit MUST recognize and
    treat specially for correctness.  Recently, the JCL code was
    modified in such a way as to defeat the recognition algorithm
    (which uses names and signatures) thereby causing the jit to
    omit the special treatment for these methods.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR1
    
    .
    The jit has been updated to recognize the new methods as special
    and treat them accordingly.
