[jbosscache-dev] Difference in starting cache in cluster?

Hi all I found weird thing, not sure if its caused by missconf or .... If I get cache instance from cache manager (app deployed in server/all/deploy) cache is clustered, as expected. However when I create cache(exactly the same config) with: DefaultCacheFactory.getInstance().createCache(); it does not create cluster. Is there any simple reason for that?
