Affected Version: 2.15 (tested with 2.15-46-g15dc942823)

What steps will reproduce the problem?
1. Create a new project.
2. Validate that the project got created just fine.
3. Check the server log.

What is the expected output?

No disturbing messages in the server log.


What do you see instead?

A disturbing log entry on the WARN level that the project could not be found on disk, immediately when the creation is performed.
WARN  com.google.gerrit.server.project.ProjectCacheImpl : Cannot find project <projectname>
java.util.concurrent.ExecutionException: org.eclipse.jgit.errors.RepositoryNotFoundException: repository not found: /path/to/gerrit/site/git/<projectname>
[traceback omitted, see below]

The project is created just fine regardless of the message. The message isn't generated again later.


Please provide any additional information below.

Both creating a project through HTTP as well as SSH results in a similar error, but with a different traceback to the same exception. I'm providing them both here below. Version: 2.15-46-g15dc942823 as downloaded from gerrit-ci.
