    Only occurs on a z196 machine
    

Local fix

  • use -Xjit:disableHighwordRA,disableHighWordGRA to turn off high
    word register allocator
    

Problem summary

  • This is a problem with the new High word register allocator
    (supported on z196 only). The register spills are not consistent
    across different out-of-line instruction sequences in the JIT
    compiler.
    

Problem conclusion

  • This defect will be fixed in:
    6.0.1 GA FP1
    .
    The JVM has been updated to prevent this crash when high word
    register spills occur.
    .
    To obtain the fix:
    Install build 20110303 or later
    

Temporary fix
