Continuing the discussion from Post-Mortem Analysis Composer Authoritative Classloader:
I was curious about the chances provided by @ChristophWurst and was not able to spot them in the documentation right away. Digging into the repo, i found them.
Unfortunately, it seems the build process of the documentation is broken at the moment. The changes are not online available under the url Classloader — Nextcloud latest Developer Manual latest documentation. Therefore i was not able to spot them.
If this is such a breaking thing, you might want to trigger a rebuild is the documentation and push that.
Cheers
