The following snipped throws NPE:

{code:java}
import org.infinispan.client.hotrod.RemoteCache;
import org.infinispan.client.hotrod.RemoteCacheManager;
import org.infinispan.client.hotrod.configuration.ConfigurationBuilder;
import org.infinispan.commons.configuration.XMLStringConfiguration;

public class Demo {

   public static void main(String[] args) {
      org.infinispan.client.hotrod.configuration.Configuration build = new ConfigurationBuilder().build();
      RemoteCacheManager rcm = new RemoteCacheManager(build);
      String xml = String.format("<infinispan><cache-container><distributed-cache name=\"%s\"><expiration interval=\"10000\" lifespan=\"10\" max-idle=\"10\"/></distributed-cache></cache-container></infinispan>", "cache");
      RemoteCache<Object, Object> index = rcm.administration().createCache("cache", new XMLStringConfiguration(xml));
      System.out.println(index.size());
   }
}
