ConcurrentModificationException in JobControl

      Description

      JobControl.toList is locking individual lists to iterate them, but those lists can be modified elsewhere without holding the list lock. The locking approaches are mismatched, with toList holding the lock on the actual list object while other methods hold the JobControl lock when modifying the lists.
