Would it be possible to bundle a Java-9-compiled module-info.class in with mockito-inline using the multi-version JAR feature (i.e. placing the class in META-INF/versions/9/module-info.class).

Although Mockito already distributes as an automatic module, the requirements on bytebuddy and the bytebuddy agent do not get resolved automatically, which results in a somewhat cryptic error the first time you try to use mocks.

I believe that the following would resolve this issue:

module org.mockito {
  requires transitive net.bytebuddy;
  requires transitive net.bytebuddy.agent;

  exports org.mockito;
  exports org.mockito.{other packages here};
}

This would reduce the confusion around JPMS for new users, and remove the need to directly depend on implementation detail.
