Wait, are you expecting compilers to actually use the implementation behind
ModuleFinder etc. in order to discover modules etc.?

When you said
   "The host system must use the Java Platform Module System (as if by
    execution of the 'resolve' method of java.lang.module.Configuration)"
I read this as requesting a compiler to perform the same operation as is
specified in that API.

Was the intention behind "must use the Java Platform Module System"
to say s.t. like "must call methods of API in java.lang.module"?
