For the four `Holder` classes in `java.lang.invoke`, the class is generated
when running jlink via `java.lang.invoke.GenerateJLIClassesHelper`. To stay in
sync with the definition you'd have to update that code. Also, since these
`Holder` classes will only contain static methods and are never instantiated
then I'm not sure it matters whether the classes are static or not.
