Follow-on to our discussion on http://jira.jboss.org/jira/browse/JBCACHE-1288 Looking at RegionManager for other reasons and noticed this bit in getRegion(Fqn, Region.Type, boolean): | // test if the default region has been defined. If not, and if eviction regions | // are in use, throw an exception since it is required. | if ((nextBestThing == null || nextBestThing.getFqn().isRoot() && !regionsRegistry.containsKey(Fqn.ROOT)) | && type == EVICTION) | { | if (log.isTraceEnabled()) | log.trace("Next best region is " + nextBestThing + ". RegionsRegistry contains a default? " + regionsRegistry.containsKey(Fqn.ROOT) + " Region type requested = " + type); | throw new RuntimeException("No default eviction region defined!"); | } | Looks like we *are* enforcing a requirement for a _default_ region.
