Local fix

  • N/A
    

Problem summary

  • A crash in JIT compiled Java code can happen if a global
    register dependency is missing, causing the compiler to not
    preserve a value which is later needed, resulting it in being
    overwritten. The problem was observed to have happened shortly
    after a STOC instruction which is infrequently generated on the
    z Systems platform.
    

Problem conclusion

  • The JIT compiler has been updated to avoid the problem by
    disabling the use of the STOC instructions.
