I've excluded the module-info.class which was leaking into the JAR via the META-INF/versions (multi module JAR) route.

I chose not to exclude the entire versions directory, because it would probably be valid for non-module-info classes to end up being shaded there at some point, and excluding those classes entirely may be bad news.

There's nothing yet in there, though. We'll also need to update the test if and when that changes.
