The issues might include more packages, but this is one example that was found:

https://github.com/infinispan/jdg/blob/jdg-7.1.x/object-filter/src/main/java/org/infinispan/objectfilter/package-info.java
org.infinispan.objectfilter package contains package-info.java file with @public marker, it should be part of the public API, but no class from this package are included in API documentation
