*** !!!! THIS BUG TRACKER IS FOR GERRIT CODE REVIEW !!!! *** Do not submit bugs for chrome/android and issues with your company's *** Gerrit setup here. Those issues belong in different issue trackers.

What steps will reproduce the problem?

Implement a UploadValidationListener plugin that returns a message to the client "foo"
Run a Git clone of a repository using Git/HTTP

What is the expected output?

The message "foo" is sent to the client and the upload-pack is terminated.

What do you see instead?

The Git client receives: error: RPC failed; HTTP 403 curl 22 The requested URL returned error: 403

Please provide any additional information below.

This regression has been caused by https://eclipse.gerrithub.io/c/eclipse-jgit/jgit/+/192677 where any HTTP status codes reported by JGit are sent as HTTP status codes to the Git client, which believes the RPC has failed.

This has been working until Gerrit v3.4 (using JGit 5.13) and then started to fail from Gerrit v3.5 (using JGit 6.x) onwards.
