JENKINS-15335: Every new job created post 1.487 have their builds and workspace disappearing on the UI. Reverted to release 1.486 and all builds and workspace are visible.
I have observed the same issue for a job that was created as well as for the job being renamed after upgrade. Again, reverting to 1.486 caused the issue to go away.
Note that all builds (run both before upgrade and after upgrade) are recorded in JENKINS_HOME and showed up after reverting to 1.486.
Jobs that were not renamed or created after upgrade were not affected.
