SpoonClassNotFoundException: cannot create shadow class

We just upgraded XWiki to Spoon 8.0.0 and obtained the following error on the CI:
> xwiki-platform-rest-api: Exception during the spoonify of the target project.: cannot create shadow class: javax.ws.rs.core.MediaType: ExceptionInInitializerError: java.lang.ClassNotFoundException: com.sun.ws.rs.ext.RuntimeDelegateImpl

I can reproduce locally by running our quality profile on the module.
Here's the full stacktrace, I'll try to produce a unit test with the failure:
```
