      Presumably there is no anonymous read access, and the Timer thread used by TryRepeatedly neglected to impersonate SYSTEM.

            Or rather anonymous DISCOVER access but not READ, an unusual configuration. Reproducible, though see JENKINS-42577 for why reproducing can be tricky.

            Perhaps core should impersonate SYSTEM in Timer threads automatically, since this is hardly the first time such a bug has occurred.

            After some back and forth I have decided that while TryRepeatedly shares some blame, a fix there does not necessarily suffice, because Queue.Task.getFullDisplayName can be called from other threads.

            Well…it is relatively risky, and this particular bug symptom has an independent workaround, so I am not sure I would recommend it for backport.

            Found another effect of this. On 2.46.x (prior to this fix), a Pipeline virtual thread dump like /job/…/…/threadDump/ will show, e.g.,

            Thread #…
	at DSL.node(node block appears to be neither running nor scheduled)
	at WorkflowScript.run(WorkflowScript:…)

            when there is a node block waiting in queue but the system has no anonymous read access. This is because ExecutorStepExecution.getStatus checks Queue.getItems, which as of SECURITY-186 is a permission-controlled call, which would in fact work if called under the authentication of the user looking at the thread dump (who presumably has READ on that job); yet StepExecution.getStatusBounded runs inside Timer, thus as anonymous.
