Local fix

Problem summary

  • Free memory wasted by hot field alignment occasionally is not
    properly accounted. We would update this stats even before we
    are sure the object is copied by the current thread. There may
    be another thread that just copied this objects a moment before.
    

Problem conclusion

  • This defect will be fixed in:
    6.0.1 SR2
    7.0.0 SR1
    .
    The fix is to move the stats update code at a later point where
    we are sure the current thread is the one that copies the
    object.
    

Temporary fix
