No. The "demo" module is an explicit module with no service configuration. It implements the SPI [1] and declares that in a module descriptor [5]. I wanted to write "resorting to the class-path". When I add a service configuration file to the explicite demo module [6] at runtime and add the location of the demo module to the class-path, the demo service is loaded ... from the unnamed module.
