I wonder if the issue is due to this bug: https://bugs.mysql.com/bug.php?id=85941 .

It got fixed for the upcoming 8.0.12 release according to the latest comment in the bug report. BUT we can't test it as https://github.com/mysql/mysql-connector-j/tree/release/8.0 is not a real repository, only the releases are published there...

Martin Šimka I don't know what to do with this bug as we don't want to skip the test when not using the 8 driver.
