EXECUTE Privilege on DBMS_SPM not sufficient

In 11.2.0.2

Here is a quick demo to show that the "ADMINISTER SQL MANAGEMENT OBJECT"  privilege is required for a non-DBA user to use DBMS_SPM even if EXECUTE has been granted on DBMS_SPM.

SQL> create user spm_test identified by spm_test quota unlimited on users;

User created.

SQL> alter user spm_test default tablespace users;   

User altered.

SQL> grant create session, create table to spm_test;

Grant succeeded.

SQL> connect spm_test/spm_test
Connected.
SQL> create table spm_test_table (id_column number primary key, data_col varchar2(15));

Table created.

SQL> alter session set OPTIMIZER_CAPTURE_SQL_PLAN_BASELINES=TRUE;

Session altered.

SQL> insert into spm_test_table select rownum, to_char(rownum) from dual  connect by level < 10001;

10000 rows created.

SQL> commit;

Commit complete.

SQL> variable qrn number;
SQL> exec :qrn := 5;

PL/SQL procedure successfully completed.

Thus, although EXECUTE on DBMS_SPM had been granted to PUBLIC and even explicitly to this ordinary user, it couldn't execute DROP_SQL_PLAN_BASELINE.  The ADMINISTER SQL MANAGEMENT OBJECT privilege was required.
