I think the example is worth running with but for now at least I don't 
know whether it will be possible to have more than one module providing 
"java" in the same module library (I'm just thinking practical matters 
like the bin directory, shared libraries in a global rather than 
module-private locations, and of course the chicken-and-egg situation 
where you implicitly choose the runtime or JDK by whatever "java" binary 
you choose to run).
