This means that our snapshots are missing doc for methods like equals:

https://guava.dev/releases/snapshot-jre/api/docs/com/google/common/primitives/UnsignedInteger.html#equals-java.lang.Object-

Note that our releases are fine. This suggests that there's something insufficient about our setup specifically on Travis. (e.g., maybe it omits src.zip there to improve performance.)

I made one attempt to fix this (based on a different theory) in 4497e2a, but it didn't work, and I've rolled it back internally (to be mirrored out shortly).

We could probably play around with submitting PRs that run ls -lR $JAVA_HOME or something, but I don't plan to look into it at the moment.
