> When running {{./gradlew :solr:core:javadoc}} discovered that if a package
> directory is missing the {{package-info.java}} file you get a VERY cryptic
> error:
>
> {{javadoc: error - fatal error encountered: java.lang.NullPointerException}}
> {{javadoc: error - Please file a bug against the javadoc tool via the Java
> bug reporting page}}
>
> I poked around and that the {{MissingDoclet.java}} method call to
> \{{reporter.print(Diagnostic.Kind.ERROR, element, fullMessage.toString());}}
> was failing, due to the element having some sort of null in it. I am
> attaching a patch and a PR.
