previous point and we would not need 3 compilation runs).
It should be in the root directory. We need to update JEP 238 or JEP 261
to properly document the proposal for how modular JARs should work as
multi-release JAR. It has been touched on in a couple of threads but
isn't written down clearly. Briefly, the proposal is that
module-info.class is allowed in META-INF/versions/<N>. When
module-info.class is in the versioned section then it should be the same
as the module-info.class in the root directory except that it might have
different non-public `requires` on java.* or jdk.* modules. It might
also have different `uses` clauses. The high level intention is that the
module API doesn't change and the differences in the module declaration
are just implementation details.
