This is still too generic I think. Can you describe a bit what kind of
rules you have in mind?
Are you mainly concerned about starting things in the right order or
more about starting or not starting things at all?
For starting things in order there are some great frameworks already.
Typically you simply define what services you offer and need using
annotations and the framework takes care of the start order.
If you are more concerned about starting or not starting things
conditionally this could be more interesting. I am not sure if and how
existing frameworks handle this case.

Well, I will say detailed background as following:
Asumming there is an application server made up many modules or OSGi
bundles, these bundles are divided into two catogories, one is
developed by the application server team,called system bundle and the
other is developed by the third part.
For system bundles, the application server has itself module starting
rule, Eg. by defining some annotations in some classes, then, runtime
can scan these annotations and while kernel is starting, it can start
these system bundles adaptivly.
However, for the third part bundles, we will have no chance or better
way liking system bundles to start them adaptivly.
If defining some metadata or rules in Spec, maybe we will have better
general way to unify such behavior.
Maybe I still have not said clearly. I am sorry...
Thanks
Tang
