Description

In this example, the test fails because the class org/hibernate/dialect/MySQL57Dialect is no longer present inside the artifact org.hibernate.orm:hibernate-core:6.4.1.Final.

The upgrade to Hibernate 6.4 was done here and here. These issues were included into the Spring Boot 3.2.1 release.

How to run this minimal example

Run ./mvnw clean test.

This example uses Testcontainers to start a MySQL Database. Therefore, a working installation of Docker is required!
