Default Error Handler
Exception:System.ServiceModel.FaultException: Default Error Handler
This exception may be thrown when a Job is copied from one Folder to another and indicates that there may be a stale ACE in either the Job or Folder's Security tab that the Job resides in. A stale ACE will look like <unknown>, and should be removed.
Removing this stale ACE from either will resolve the issue.
A stale ACE is created when a user or group from Active Directory was added to a JAMS ACL, and then removed from Active Directory.
