        throw new SecurityException("class \""+ name +

[FIXED JENKINS-31718] Integrated a new version of Remoting with a fix for a regression in concurrent socket connections.

(cherry picked from commit e6d8500d)

In the project meeting today we decided to pull this in.

[JENKINS-31718] Integrated a new version of Remoting

- The previous check was to narrow.
- We now check on AccessControlled (which is implemented by Item)
- We now also check on Permission.READ (which is the generic read permission)

This should allow subtasks who's task may not be an Item to at least implement AccessControlled to alow visibility.

There remains an open question as to whether tasks that are not AccessControlled should ever be visible in the UI
