IJ20311: A SIGFPE ERROR IS RAISED IN JAVA JIT COMPILED METHOD USING DATA ACCESS ACCELERATOR LIBRARY

APAR status

  • Closed as program error.

Error description

  • Error Message: A SIGFPE (Floating Point Exception) error occurs
in JIT compiled code on z14 or higher architectures. Other
architectures (i.e x86, PPC) and older Z CPUs are not effected
by this problem.
.
Stack Trace:
.

Local fix

  • The problem can be worked around by specifying the Java virtual
machine option -Xjit:disableStoreSinking. This may have a small
impact program performance.

Problem summary

  • The Java JIT compiler may perform a late optimization that sinks
a store of a node that performs a BinaryCodedDecimal operation.
This results in invalid IL as an assumption about the IL is
broken. As a result, incorrect code is generated on the Z
platform.

Problem conclusion

  • This problem has been addressed and the JIT Compiler will no
longer sink stores of Binary Coded Decimal operations.
.
This APAR will be fixed in the following Java Releases:
 8 SR6 (8.0.6.0)
.
