As part of this I've changed the implementation to not silently skip services configuration files or contents that don't parse as identifiers. Also a small change to ModuleDescriptor.Builder in preparation for other changes.

This looks fine.

ModuleFinder.of spec describes the possible cases where FindException may be thrown by a module finder’s find or findAll methods.

It would be useful to have the @throws FindException if an error occurs finding all modules in find and findAll methods to link to such description.

As I commented offline, it’d be good to link to the definition of legal package name but looks like we need to add that in some appropriate spec before we can do that.
