Local fix

  • n/a
    

Problem summary

  • The problem manifests when we read the high performance counter
    from Windows OS. If the value returned is less than 1000000 then
    we crash (due to divide by zero). The fix is applicable "only"
    on those systems where the value returned by
    QueryPerformanceFrequency() is lessthan 1000000
    

Problem conclusion

  • This defect will be fixed in:
    6.0.0 SR9
    5.0.0 SR12
    .
    JVM has been updated to take care of this divide by zero
    scenario.
    .
    To obtain the fix:
    Install build 20100410 or later
