About KVCache.addListener

[zjfplayer]

My test code：

String root = "test1";
    KVCache nc = KVCache.newCache(
            kvClient, root, 10
        );

nc.addListener(new ConsulCache.Listener<String, Value>() {
            public void notify(Map<String, Value> newValues) {
                for(String key:newValues.keySet()){
        System.out.println("1==="+newValues.get(key).getKey()+":"+newValues.get(key).getValueAsString().get());
                }
            }
        });
        nc.start();

I suppose newValues will contains keys like "test1","test1/",but why newValues contains keys like "test1*/",is it bug?
