Description

Database owner attempts to revoke select privilege from a schema owner's own table but the owner later can still select from the revoked table. Behavior is inconsistent. e.g.:

ij version 10.2
ij> connect 'jdbc:derby:wombat;create=true' user 'user1' as user1;
WARNING 01J14: SQL authorization is being used without first enabling authentication.
ij> connect 'jdbc:derby:wombat' user 'user2' as user2;
WARNING 01J14: SQL authorization is being used without first enabling authentication.
ij(USER2)> create table tshared0 (i int);
0 rows inserted/updated/deleted
ij(USER2)> – db owner tries to revoke select access from schema owner user2
set connection user1;
ij(USER1)> revoke select on user2.tshared0 from user2;
0 rows inserted/updated/deleted
ij(USER1)> set connection user2;
ij(USER2)> select * from user2.tshared0;
I
-----------

0 rows selected
ij(USER2)>
