Spring @DataJpaTest with @TestContainers in JUnit 5

This is an extension to Spring @DataJpaTest with JUnit 5 the main difference is the addition of test containers.

I tried to keep things at minimum in a git-repo sample.

The test is pretty straight forward

@DataJpaTest
@Testcontainers
@ContextConfiguration(classes = {
        DemoApplicationTests.Config.class
})
@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
class DemoApplicationTests {

    @Autowired
    private Artifacts artifacts;

    @Test
    void contextLoads() {
        assertThat(artifacts).isNotNull();
    }

    @Container
    private static final MySQLContainer<?> MYSQL = new MySQLContainer<>("mysql:5.7");

    @Configuration
    static class Config {
        @Bean
        public DataSource dataSource() {

            final DriverManagerDataSource dataSource = new DriverManagerDataSource();
            dataSource.setUrl(MYSQL.getJdbcUrl());
            dataSource.setUsername(MYSQL.getUsername());
            dataSource.setPassword(MYSQL.getPassword());

            await().pollInterval(Duration.ofSeconds(2L))
                    .atMost(Duration.ofMinutes(2L))
                    .until(() -> {
                        try (final Connection c = dataSource.getConnection()) {
                            c.prepareStatement("select 1 from dual");
                            return true;
                        } catch (SQLException e) {
                            return false;
                        }
                    });

            return dataSource;

        }

    }

}

The main application I kept to a minimum as well

@SpringBootApplication
@EnableTransactionManagement
@EnableJpaRepositories
@EntityScan
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

But running the test I get the following stack trace segment:
