I think I saw a discussion about fixing this since the new Visual Studio
compiler also complained about it, or so. It might even be fixed in jdk/hs.
Not clear what triggered them, but my guess is an Xcode update.
If you updated Xcode, and are using that instead of jib for building,
then yes, that's likely.

Is this a known problem? Can anyone reproduce?
