The PTs seem to work fine, so it's not fatal, but something is clearly broken.

Can you add more details about your environment, like Docker version, OS, etc?

[ksobolew]

Sure, it's plain Docker Desktop on Mac (4.3.1 (72247), Engine: 20.10.11), Zulu Java 17

memoryStats fields are nullable. and my IDE indicates a warning here
