[jboss-as7-dev] deprecate/remove or change ServerEnvironment.getModulesDir() which returns a single File representing the AS7 Modules directory path....

[Thomas Diesler]

Both, the modules and the bundles directory are repositories of 
artefacts that can be referenced at boot time (or later). We separated 
the two because we saw dependencies from modules to osgi bundles show 
up. Also it would be wrong to place a modules.xml (i.e. hard coded 
dependency definition) alongside a bundle.

I suggest to abstract this and introduce a notion on Repository that can 
be referenced from the ServerEnvironment. The initial implementation 
could be File based.

Repositoy {

     URL getModule(String name, String slot);
}

for example. You could then have a RepositoryModuleLoader. This is just 
a conceptual idea - please excuse the lack of detail.
