Question about the mapping of oopDesc and KlassOop

I have a question about the java object layout in Hotspot.
In hotspot, a oopDesc respesents a java object, oopDesc contains a pointer
to a klassOop instance. Is the relation  between the instance of oopDesc and
the instance of klassOop one to one mapping ? Or multiple oopDesc  instances
can share one klassOop?
Thanks a lot!
