I've recently filed two PRs that exclusively changed classes in the java.nio.file package. Neither PR was automatically labelled by the bot. Every time I got this message:

@pavelrappo To determine the appropriate audience for reviewing this pull request, one or more labels corresponding to different subsystems will normally be applied automatically. However, no automatic labelling rule matches the changes in this pull request. In order to have an "RFR" email sent to the correct mailing list, you will need to add one or more applicable labels manually using the /label pull request command.

Please fix this. I presume, that the respective rule should include java.nio.** (java.nio and all its "subpackages").
