NoSuchMethodError when using agent and modules (JPMS) and selenium

I'm trying to add agent to my project but see the issue during startup (stack trace below). I think issue is that:

1. Project uses java module system (JPMS)
2. Project has selenium-remote as dependency which has opentelementry as dependency

In combination it causes that incorrect version of autoconfigure loaded (shaded vs unshaded).

As stated by @laurit

This is a bug in opentelemetry agent. Agent uses a custom class loader to load most of the agent classes. Unfortunately when running with jpms agent classes that are present in application get loaded from application instead of agent.

unfortunately we have to revert the fix for this (#5406), so re-opening

Looks like we don't need to revert (#5408), closing 🥳
