roller + jdo/jpox

[Jeff Blattman]

i see some work going on to port from hibernate to jdo. sorry, i am new 
here and i don't know the status / rational for that, but i'd like to 
add my comments.

i have experience using jdo, and jpox in particular, with a commercial 
product. first, you probably already know this, but jdo is dead (from a 
spec perspective anyway). it will be phased out in favor of ejb3 
persistence. maybe that transition will be graceful, maybe not. i see 
jpox has ejb3 on their roadmap, but not sure what that means.

second, jpox has really, very atrocious performance issues. the jpox 
folks admit that performance is a low priority, as they are an ri. if 
someone wants the details on this, i can dig them up.
