Umstellung Spring Boot V1.3.5 auf V1.4.M2: Probleme mit EHCache

Nach der Umstellung einer insgesamt schon älteren Spring Boot Anwendung von Spring Boot 1.3.3 auf 1.4.M2 tritt der folgende Fehler auf:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ds2EntityManagerFactory' defined in class path resource [de/ordix/twods/config/Ds2Database.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: ds2] Unable to build Hibernate SessionFactory
