Description

When overriding a method as `protected` with a super method being package-private (no modifier in Java or `@PackageScope` in Groovy), compilation fails with an error similar to this:

...
exampleMethod(java.lang.Object -> java.lang.Object) in com.example.Child cannot override exampleMethod in com.example.Base; attempting to assign weaker access privileges; was package-private
...

This edge case seems to be missed at GROOVY-8651.
