How would returning copies of the admin object help with this?

I think the spec indicates copies should be returned.  We used to  
return proxies.  I've always wondered what the point of a lot of the  
jndi spec was.  I've taken the view that the important part of the  
spec is for jndi to act like a hashmap and that since our jndi is in- 
vm only and not persistent lookup speed is pretty much the most  
important bit.

Could you explain in more detail what you don't like about this and  
what you want instead?
