hi there,

i found a strange nullpointer, maybe someone can enlighth me..


here the test case


public class Test {

    public static void main(String [] a) {
        GrizzlyWebServer ws = new GrizzlyWebServer(12345);
        ws.addGrizzlyAdapter(
                new GrizzlyAdapter() {
                    @Override
                    public void service(GrizzlyRequest grizzlyRequest, GrizzlyResponse grizzlyResponse) throws Exception {
                        HttpServletRequest httpReq = new HttpServletRequestImpl(grizzlyRequest);
                        httpReq.getSession(true).setAttribute("a", "a");
                    }
                }
        );
        try {
            ws.start();
        } catch (IOException e) {
            e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates.
        }

    }
}


just exec it, i get a NullPointer on setAttribute (getSession return actually a object, is the method setAttribute that throw exception)
