until now, @DataJdbcTest did not need a dependency to spring-boot-starter-data-jdbc. I think this is a non-intuitive change. Many people will wonder why they got:
Caused by: java.lang.NoClassDefFoundError: org/springframework/data/jdbc/repository/config/AbstractJdbcConfiguration

slice test annotations can't bring a dependency when they're used. The issue addressed an inconsistency with regards to @DataJdbcTest. If you want to test the JDBC slice of your app and you don't want to use Spring Data, you have to use @JdbcTest.
