Closed as program error.
Error description
Error Message: The JRE reports the following error message Type=Illegal instruction vmState=0x00000000 . Stack Trace: N/A . This problem can only happen on IBM Z on z10 machines
Local fix
This problem can be avoided using the following command line option: -Xjit:disableMaxMinOptimization
Problem summary
The JIT compiler has an optimized version of the max/min operation which uses the LOCR instruction which is not available on z10. A guard was missing for this operation so it was possible for the JIT compiler to generate on LOCR on z10 which results in an illegal instruction exception when executed.
Problem conclusion
The following commit fixes this problem. https://github.com/eclipse/omr/commit/04c6437444222d4ad94c5d3e00 da6c29e17dd389 .
