Local fix

Problem summary

  • The JVM didn't invalidate the CRC after the items in the shared
    cache were marked stale, resulting in the CRC check failure.
    

Problem conclusion

  • The JVM has been changed to always invalidate the CRC if the
    items in the shared cache are marked stale.
