[JENKINS-32765] As I am not *adding* a new import, I will annotate with `@CheckForNull`

Of course the import being used is in a package name that is reserved for artifacts produced by a JSR... and the JSR that the dependency is claiming to come from has not actually published anything... thus whoever produced the artifact has broken the JSR policy... and it is also not safe for us to actually use these annotations as we do not know what a JSR may change on the road to actually providing this... but that is a war for a different PR
