>             Project: Derby

>          Components: SQL
>    Affects Versions: 10.2.1.6

> Revoking a privilege on a table will currently cause the DependencyManager.invalidateFor() to be called on the table's TablePermsDescriptor with the action=REVOKE_PRIVILEGE. However, the prepared statements that refer to that table are dependents of the table's TableDescriptor, but NOT its TablePermsDescriptor, so the statements are not invalidated after revoke.
> This problem is currently hidden by the fact that authorization is checked on every execution, but this will change when language result sets are no longer reused (see DERBY-827).
