APAR status

  • Closed as program error.

Error description

  • Error Message: Either a JVM crash, with vmstate=0x0, or an
    unexpected Java exception are seen in customer code near a call
    to Object.clone.
    .
    Stack Trace: N/A

Local fix

  • Using the JVM option -Xjit:disableGlobalVP,diableLocalVP will
    cause this failure to stop occurring. The use of this option may
    cause a significant degradation in performance to be seen, and
    is expected to at least noticeably reduce the performance of
    most workloads.
    

Problem summary

  • A JIT compiler optimization contained code that incorrectly
    optimized calls to java.lang.Object.clone in specific
    circumstances.
    

Problem conclusion

  • The problematic JIT compiler optimization was corrected to
    ensure that calls to java.lang.Object.clone are handled
    correctly in all cases.
