so there's no change in the paths of the classes referred to in these stacktraces?

Nope: please see the linked explanation in the PR description and scroll down to "Revised naming for packages and Maven artifacts". Also these are part of an example stacktrace and don't figure into the unit tests at all.

This is doesn't not seem to exist right now in the googlesource repo?

So, that's going to be an invalid documentation link?

    Note: android.support.* is in the process of being converted to androidx.*,

i'm not sure if we should refer to this so specifically.
what is the plan to remove this time-sensitive info?

Might be easier to simply change the reference in code block?
