"object could not be invalidated"
*Cause: A call to the DBMS_UTILITY.INVALIDATE routine failed. This error
occurred because the object type of the object specified by the
p_object_id argument is not one of the types that can be handled
by this routine. Alternately, the object was an object type
specification with table dependents, or the object was the
specification of the STANDARD, DBMS_STANDARD, DBMS_UTILITY
package, or the body of the DBMS_UTILITY package.
*Action: Call DBMS_UTILITY.INVALIDATE only on supported object types.
