[jboss-osgi-dev] AS7-5639 Add OSGi Launcher to AS7

[David Bosschaert]

I think it would be fair to assume that the org.osgi.core packages are 
shared from the initiating classloader - the one that kicks off the 
framework launcher. This is what the TCK does too, it puts these 
packages explicitly on the org.osgi.framework.system.packages.extra 
property and this is how I have it currently implemented.

I originally implemented a bridging approach where these classes were 
separate (so one instance of class X owned by the caller and one 
instance of class X owned by JBoss Modules) but this doesn't work when 
you are passing objects created by JBOSGi back into framework APIs. For 
example, if you call BundleContext.getService(ServiceReference sr) our 
implementation actually expect our own ServiceReferenceImpl to be passed 
in, which clearly doesn't work with the bridging approach (or it will 
get very complicated).

Cheers,

David
