I followed Oliver Gierke's latest test example and I get the same error he mention. With BETA2 works but in the latest Snapshot not. Also, the example have nothing to do with Spring Data at all, is just Hibernate.
@Steve I know you have to schedule your time, but the example is pretty short and simple, it won't take you much time to check it and see that it truly fails.
