ORA-06502 "number precision too large" only in PL/SQL Developer

Question

There is a package with type.

CREATE OR REPLACE PACKAGE MY_TYPES IS
PRAGMA SERIALLY_REUSABLE;
  SUBTYPE my_number IS NUMBER(3,0);
END MY_TYPES;
/

There is a procedure:

DECLARE
  PROCEDURE print(my_number_i IN my_types.my_number) IS
  BEGIN
    dbms_output.put_line(my_number_i);
  END;
BEGIN
  print(my_number_i => 35);
END;
/

The problem is that such a call gives an error in PL/SQL Developer.

ORA-06502: PL/SQL: numeric or value error: number precision too large.

But if you substitute the value my_number_i => !=35, the procedure is completed.

However, if you run it from SQL Developer, everything works. If you run it via SQL*Plus, it also works. It only does not work from PL/SQL Developer.

Please tell me what the problem might be?
