Research direction

Start at the JDBC driver connection-property handling and trace how user/password properties are extracted from the Properties passed to DriverManager.getConnection. Extend the same path for kyuubiClientPrincipal and kyuubiClientKeytab, then verify that connections created with those properties use them for client authentication.
