I'm not muting this as it has only failed once. I think it will be more helpful to get some additional data if this is flaky. If I come across another failure today, I'm going to mute it

This failed again in November (see #80496) and also in:
https://gradle-enterprise.elastic.co/s/6kmave7jxtdie
https://gradle-enterprise.elastic.co/s/q7odku5tfezuu

I'm going to mute.
