Multiple module directories is not an app server feature; it's a feature of the particular module loader implementation that we use by default.  The app server has no control over the topology of the modules; in fact it could be launched by a completely alternative module loader that doesn't even use the file system.

If you need a database of system modules and their dependencies you'll have to maintain that external to the module system because there is no contract there.  The best place to maintain this sort of module database would probably be within the OSGi subsystem.  There is currently no contract to enumerate the list of potentially loadable modules from a module loader.

> If the AppServer supports the notion of multiple directories where modules can get loaded from, the ServerEnvironment should reflect that properly. I cannot just load a module on trial/error basis because we use the Repository for impact ananlysis. i.e. Find the modules/bundles that provide the transitive set of capabilities for a given set of requirements (without modifying the runtime).
