In DP 6.0 there's a strange error message when one of the objects being copied
(i.e. is to be copied) is being written while the object copy session
starts. Then the whole copy session aborts with nothing being
copied. Unfortunately there's no method to "Restart failed objects" (like for
failed backup objects). I also noticed that you cannot set an owbner for a
object copy session.

Are those "features", or are those bugs?
