Hi,

I upgraded a jenkins installation to 1.562 today, which made all matrix jobs disappear from the front page, i.e. they can no longer be viewed or run.

Here's a snippet from the logs:

This is with jenkins 1.562 (from the Debian package from jenkins-ci.org). The new Matrix Project Plugin (version 1.0) is installed and enabled.

Please let me know if there is a temporary workaround to make the jobs accessible again and/or what the proper fix for this is.

The job files are still there (/var/lib/jenkins/jobs/foo/config.xml etc).
