Implementing java2 security can create very complex code structures  
that are difficult for people to read, debug, maintain, and improve.   
If someone wants to implement this (and I would say that's a huge  
if), I would like to see the effort focused on making sure the code  
is still readable.

I really like kevin's suggestion to just pop in a wrapper if you care  
about Java2 security.  Or maybe we can create a doPriv subclass of  
EMF, for those that care (of course open out calls like lifecycle  
callbacks would need an exit doPriv).

In my experience, I've never seen someone use Java2 security in
