When Jenkins is restarted, it fails to load most of the builds. The jenkins.log file contains many exceptions like this one:

We're using Jenkins 1.445 but I think the problems is present for several versions; I can't tell when it started.

The consequence is that many builds are missing in the UI. If the last build of a job is missing, a new build may be triggered (ie. for those depending on a VCS commit).

A workaround is to click on "Reload Configuration from Disk" in the "Manage Jenkins" page. This properly reloads all builds and they are visible again.
