MySQL container shuts the container down during setup and later on starts it again. However, maven docker plugin waits for [Entrypoint] MySQL init process done. Ready for start up. string in the log, which happens before container is started. As a result, tests which connects to the database at the very beginning of the tests (e.g. IncrementalSnapshotIT) may fails with

as the MySQL server is not fully started yet.
This is random failure as CI is passing without any issue and on my machines it worked reliably ~2 weeks ago. Now, it always fails.
