[forge-dev] Help needed

FYI - This is how it should look when you reproduce the problem. What's
happening in this case is that Forge is starting up just fine in the test,
but for some reason the ContainerServiceExtension is not intercepting the
service classes deployed in one of the addons.

This makes me think that the system classloader is being scanned properly,
but that there is a subtle problem with the module structure defined by
AddonModuleLoader that is preventing these classes from being scanned.
Either that, or the ModularURLScanner class requires modifications to work
within the Surefire environment.
