Also I find it confusing that the method most prominently used for
inserting new objects shouldn't do so for detached instances.
There is a bunch of history that you should look at, most of which is
in the jdo-dev archives. Bottom line, we used to have a different API,
attachCopy, but we looked at what it had to do for transient and
detached instances and decided that it wasn't worth making a different
API for attaching detached instances.
That particular behaviour of attachCopy() wasn't really specified, but
it was pleasant JPOX-specific behaviour, if I remember correctly. I saw
the discussion and I didn't see where inserting the instances would be
forbidden by the spec, and still I don't see where it says that,
especially in the light of 12.6.7. Please excuse my ignorance, where
does it say that?

Hi,
What happens when we invoke makePersistent on a detached instance
that was
deleted by another isolated process? I suspect that we raise an
exception
instead of reinserting it for a second time. Is that right?
Maybe this can be clarified in the spec.
