Thomas Lang, another option to workaround the spring issue until spring-boot decides whether to address it or not would be to explicitly override the configuration that autoconfigure uses to force it to use the default Hibernate strategies. To do that, just setup the spring configuration as follows and you'll get the default behavior.

spring.jpa.hibernate.naming.implicit-strategy=org.hibernate.boot.model.naming.ImplicitNamingStrategyJpaCompliantImpl
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
