[19c EE] Lost privileges when created APPLICATION CONTAINER FROM PDB

Hi all

I am currently tried to create pluggable database as APPLICATION CONTAINER from an existing PDB, and i noticed that the "ADMIN USER" lost privileges.

Here is my test :

I have a PDB (call PDB_SRC) created with DBO as "admin user". This user have PDB_DBA role.

This user can, for example, create user or lock / unlock user

1 - I create a pluggable database from this PDB_SRC using :

create pluggable database PDB_TRG from PDB_SRC ;

alter pluggable database PDB_TRG open;

2 - i connect with DBO on PDB_TRG and i can do "ALTER USER test ACCOUNT LOCK;" - no problem
