sure, but how does this work? The osgi subsystem loads the framework 
from a module which loads the org.osgi.framework packages from another 
module. The osgi system packages that can be configured through 
framework properties still come from the modules hierarchy and not from 
the syscp. So I wonder how anything except java.* and some system 
packages defined though Modules can be used from outside the AS.
