Oracle Database Discussions

I've been exploring the capability of outline but found some problem.
The outline for SQL statements located "in" the stored procedure is created,
but not reused.

See following example.

select * from v$version;

BANNER

PL/SQL Release 10.2.0.3.0 - Production

TNS for Linux: Version 10.2.0.3.0 - Production

-- Enable "create outline"
alter session set create_stored_outlines = true;

-- Create stored prodecure 
create or replace procedure outline_proc
authid current_user
is
  v_cnt number;
begin
  select count(*) into v_cnt from pl_test p1;
end;
/

-- Enable "Use outline"
alter session use_stored_outlines = true;

-- Execute it several times
exec outline_proc;
exec outline_proc;
...

-- Check user_outline
select category, used, sql_text from user_outlines;
CATEGORY	USED	       SQL_TEXT
------------       -----------       --------------------------------------------------
DEFAULT	          UNUSED	SELECT COUNT(*) FROM PL_TEST P1

Is this an expected behavior? If so, is there any way to reuse outline under this situtation?

Thanks in advance.
