Description

The various xattr methods in DFSClient specify AclException in the call to RemoteException#unwrapRemoteException. It's impossible for the xattr APIs to throw AclException. Since encountering AclException would be an unexpected condition, we should not unwrap it so that instead we maintain the full stack trace.
