PLS-00103: Encountered the symbol "EXCEPTION"

Hi,

on 11.2.0.4 , I ran

DECLARE 

  i number(1); 

  j number(1); 

BEGIN 

    FOR j IN 1..3 LOOP 

     dbms_output.put_line('i is: '|| i || ' and j is: ' || j); 

     exception

     when others then

     null;

   END loop ; 

  END; 

/

And I had:

Error report -

ORA-06550: line 9, column 10:
