SQL & PL/SQL

Hi all,
may be i found an oracle error.

SQL> select * from ALL_DEPENDENCIES  where name = 'EMP';

OWNER  NAME TYPE    REFERENCED_OWNER               REFERENC REFERENCE REFERENC DEPENDEN
------ ---- ------- ------------------------------ -------- --------- -------- --------
PUBLIC EMP  SYNONYM HR                             EMP_PKG  PACKAGE            HARD

so this tell me that the type is a SYNONYM, while the following

SQL> select object_name,object_type from user_objects where object_name='EMP';

OBJECT_NAME OBJECT_TYPE
----------- -----------
EMP         TABLE

tell me that this is a table and that is true, is this an oracle bug?

Thanks so much
Francesco
