> InvalidableEntityInstanceCache.start() throws an NPE on line 123:
> String groupName = emd.getDistributedCacheInvalidationConfig().getInvalidationGroupName();
> Problem is EntityMetaData.getDistributedCacheInvalidationConfig() will return null in the usual situation where there is no "cache-invalidation-config" element. In 4.x this doesn't occur because EntityMetaData.importFromJBossXml() ensures that a default CacheInvalidationConfigMetaData is created.
> Solution is to lazy initialize the default CacheInvalidationConfigMetaData in EntityMetaData.getDistributedCacheInvalidationConfig().
