Steve Ebersole commented on HHH-5303:
-------------------------------------
>From what I can tell 'hibernate.ejb.classcache' settings take effect no matter what because they kind of operate outside of the caching annotations stuff. I guess this looks kind of "non-unified". It almost seems to me that 'hibernate.ejb.classcache' is trumping all else. Perhaps that was the original design decision here, I do not know.
The only ways that I can see cacheAnn as null is that you did not specify @Cache and either:
# You used SharedCacheMode.NONE or UNSPECIFIED (or did not specify)
# You used SharedCacheMode.ENABLE_SELECTIVE and had @Cacheble(false) or did not specify @Cacheable
# You used SharedCacheMode.DISABLE_SELECTIVE and had @Cacheble(false)
> @Cachable has no effect

> Key: HHH-5303
> URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5303
> Project: Hibernate Core
> Issue Type: Bug
> Components: caching (L2), entity-manager
> Affects Versions: 3.5.2
> Environment: Tested on HSQL (included in testcase) and MySQL database
> Reporter: Paul Bakker
> Attachments: testcase.zip

> 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
