Looks pretty good.  FYI, as far as I can tell, your 'j2ee.*' extensions 
aren't compliant, because they can bypass middleware modifications to the 

(I wonder if perhaps the current mechanism to prevent middleware bypassing 
is too heavyweight?)

I haven't had time to read all of the source code yet, so I'm not sure if 
that's the only compliance issue, but that's the only one I've seen in your 

By the way, if you do implement pooling of application objects to bypass 
their single-threadedness, I think the only really safe way to do that is 
by having a separate Jython interpreter for each one.  A single-threaded 
application is going to assume it can use module-level globals without 
conflicts, so just creating duplicate application objects isn't going to 
resolve that issue.
