Database Init fails after upgrade to Spring Boot 2.4.x

After upgrading from Spring boot 2.3.5.RELEASE to 2.4.x our application cannot initialise the database connection using Exposed anymore. The full stack trace is attached below.

The piece of code where the exceptions happens:

    @Bean
    fun initDatabase(dataSource: DataSource): Database {
        val connect = Database.connect(dataSource)
        transaction {
            SchemaUtils.create(
                OrderTable,
               ***REDACTED***
            )
        }
        return connect
    }

The datasource injected in this function is just a datasource with username, password and URL of type MariaDbPoolDataSource where the URL is: jdbc:mariadb:aurora://***REDACTED***-***REDACTED***.cluster-***REDACTED***.eu-west-1.rds.amazonaws.com:3306/***REDACTED***?connectTimeout=60000&minPoolSize=0&maxIdleTime=60

Any ideas what is going on?

Thanks for your help @Tapac , I’m going to close this issue, as it has been resolved for me.

Interesting, with Exposed 0.32.1 and with spring boot 2.5.1 it does seem to work! But what has changed, I wonder…
