[hibernate-dev] Cache testing & JCache

The initial hibernate-jcache code would create JCache Cache instance "on the fly" as they were needed if not already defined. As part of a discussion about JCache support, it was agreed that this should not happen. To be clear... the integration code calls javax.cache.CacheManager#getCache(java.lang.String). If we are returned nothing, its a choice between throwing an exception or calling javax.cache.CacheManager#createCache. The consensus among the cache providers was that an exception should be thrown as the standard outcome. However, in testing I wonder if we want to allow that "on the fly" creation to happen. Opinions? And if not, thoughts on how to best pre-define all the needed Cache instances?
