How to Reproduce

1. The ”test“ user has rw permission under public namespace;

2. The error code is as follows：

public class Test {
        public static void main(String[] args) throws Exception {
            Properties properties = new Properties();
            properties.put("serverAddr", "127.0.0.1:8848");
            properties.put("namespace", "");
            properties.put("username", "test");
            properties.put("password", "123456");
            NamingService namingService = NamingFactory.createNamingService(properties);
            List<Instance> list = namingService.selectInstances("provider", true);
            System.out.println(list);
    }
}
