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.

Temporary fix
