IllegalArgumentException during TreeCache instantiation

With the current version it is not possible to create an instance of TreeCache. I'm using the cache inside JBoss 7.1.2 Final. The following lines worked in earlier versions of the cache api:

org.infinispan.Cache<String, Object> infiniCache = this.cacheContainer.getCache(cfg.getName());

TreeCache<String, Object> tc = new TreeCacheFactory().createTreeCache(infiniCache.getCache());

Now the method createTreeCache(..) throws an java.lang.IllegalArgumentException: This adapter only works with CacheImpl, not with DelegatingCach
