Error description
Error Message: a 0C7 Data Exception or Decimal Overflow generated by a Binary Coded Decimal instruction causes the JVM to terminate. . Stack Trace: N/A . This problem only affects z Systems running z/OS
Local fix
If the -Xrs Java command line option is used, then the DAA optimization also needs to be explicitly turned off using -Xjit:disableIntrinsics
Problem summary
The Data Access Acceleration (DAA) optimization requires complete JVM signal handling functionality. The -Xrs option reduces the JVM's signal handling capabilities. -Xrs should implicitly turn off DAA but it was discovered that this was not the case. The result is that if -Xrs is used and DAA is invoked, then it is possible that a DAA instruction could generate an interrupt which the JVM cannot handle under -Xrs and thus the interrupt causes the JVM to unexpectedly terminate.
Problem conclusion
The JIT compiler has been updated so that -Xrs does turn off DAA. . This APAR will be fixed in the following Java Releases: 7 R1 SR4 FP5 (7.1.4.5) 8 SR4 FP5 (8.0.4.5) .
