GridException Failed to add no-op logger for Log4j on GridGain startup

I'm having trouble to get started with gridgain, i'm using the xml configuration file that come with gridgain examples example-cache.xml (Is there a simpler configuration file?). When I start gridgain as follows I got a GridException:

public static void main(String[] args) throws GridException, URISyntaxException {
  URL url = GridgainCache.class.getClassLoader().getResource("gridgain.xml");
  String filename = url.toURI().toString();
  System.out.println("Reading gridgain conf from: "+filename);
  Grid g = GridGain.start(filename);
  ...
}

Here is full stack trace:

Exception in thread "main" class org.gridgain.grid.GridException: Failed to add no-op logger for Log4j.

Do I need to configure log4j? i'm using slf4j.
