In JDK-8316234 it was suggested there might be a gcc bug involved: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87489 Having read through that bug, I'm inclined to agree that's probably involved. Much as I hate warning suppresions, I think a better solution here is to use PRAGMA_NONNULL_IGNORED, along with a comment referring to that gcc bug, and also mentioning that it might require some distro-specific gcc patch, since not seen with vanilla gcc release.

Mmm, I see. Agreed.
