-------------------------------------

What do you specify for javax.persistence.SharedCacheMode?  The corresponding config property name is 'javax.persistence.sharedCache.mode'.  Its default value is SharedCacheMode.UNSPECIFIED which states:

Caching behavior is undefined: provider-specific defaults may apply.

> The JPA 2.0 @Cachable annotation has no effect at all. Just putting @Cachable on a class is not enough to enable caching. You must also configure a concurrency strategy with either @Cache or a hibernate.ejb.classcache setting in persistence.xml. 
> If those settings are in place, @Cacheble still has no effect. Entities are cached, but @Cachable(false) doesn't change this behavior. 
> I included a Maven example project that tests this behavior. The project has two profiles to switch between Hibernate and EclipseLink:
> mvn -P hibernate clean test
> mvn -P eclipselink clean test
