One thing that is not clear is whether the yyy in "provides xxx with
yyy" directive of module declaration must be a concrete class and a
subtype of service type when the service is obtained via a static
method. For example, is the following a valid configuration: Service
type A, implementation class B (a subtype of A), static method
declared in C (unrelated to A) with return type B (or A or anything
between A and B?).
If yyy defines the static factory method then it does not need to be a
sub-type of xxx, the return type from the public provider() method just
needs to be xxx or a sub-type of. So the example is okay, no need for C
to extend/implement A.
I should note that the implementation isn't aligned with this yet but
there are updates to both javac and SL coming that will align it with
the current proposal.
