Wrapping of type specification seems not to be possible, when accessible by clause is used

Hi community,

I just found an unexpected limitation of the pl/sql wrapping utility (Oracle DB 21c Release 21.9) when I wanted to wrap the following type specification:

CREATE OR REPLACE TYPE tp_test_internal
AUTHID DEFINER ACCESSIBLE BY (TYPE tp_test)
AS OBJECT
(
id INTEGER
);
/

When run the wrapping utility with command

wrap iname=TP_TEST_INTERNAL.tps ONAME=TP_TEST_INTERNAL.wrp

I got the following output on screen

PL/SQL Wrapper: Release 21.0.0.0.0 - Production on Sa Mrz 4 22:14:01 2023
