Paul Bakker commented on HHH-5303:
----------------------------------
I did another test.
@Cacheable(true)
No @Cache
The only cache related setting in Persistence.xml:
{code}
<property name="javax.persistence.sharedCache.mode"
value="ENABLE_SELECTIVE"/>
{code}
After executing the determineCacheSettings the cacheAnn instance is as follows:
region = "demo.entities.Employee"
usage = "NONE"
That seems to be wrong. How does it figure out the cacheconcurrencyStrategy? That shouldn't be NONE by default because that defeats the purpose of having a standardized @Cacheable annotation.

> 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
