circular dependency issue

[Jeremy Boynes <je...@coredevelopers.net>]

Dain recently added logging and serverinfo into the core module. This is 
causing me an issue as I need to use these in the deployer, but core 
depends on deployment so gets built later.

I would like to suggest we trim the dependencies a bit and add a new 
module "system"

This would then make the tree:
kernel
system
deployment
core (going away soon)
...

This would mirror the runtime dependency tree where we build the 
"system" config (containing logging, serverinfo, repository) first, and 
then make the "J2EEServer" config it's child.

Does this make sense?

There is no more logging code in common... It has all been moved to the 
logging gbeans

That is exactly what happens.  Logging is weird because it is used 
before the server is started (or even really exists).

Common contains helper classes that are not GBeans and hence it does not 
depend on kernel (and vice versa). The things in system are all GBeans.

Logging is now a hybrid - it starts off not a GBean and then gets 
switched into one when the system has booted far enough. At least, I 
think that's the idea, Dain has the details.

Where does common fit into this?
Is Logging is something that could fit into common.
