UserSetupUrl NullPointerException in checkid_immediate

What steps will reproduce the problem?
1. Create a ServerManager, don't set the UserSetupUrl (or
manager.setUserSetupUrl(null) )
2. Execute a checkid_immediate request that will cause an negative response

What is the expected output? What do you see instead?
In the protocol version 2.0 userSetupUrl should not be an issue.

What version of the product are you using? On what operating system?
0.9.5

Please provide any additional information below.
public static void main(String[] args) throws Exception 
    {
        BasicHttpRequest request = new BasicHttpRequest("GET",
"/openid?openid.mode=checkid_immediate&" +
                "openid.ns=http://specs.openid.net/auth/2.0&" +
                "openid.claimed_id=http://www.test.com.br/openid/user&" +
                "openid.identity=http://www.test.com.br/openid/user&" +
                "openid.return_to=http://mysite.test.com/openid");

        ServerManager openidManager = new ServerManager();
        openidManager.setOPEndpointUrl("http://www.test.com.br/openid");
        URI uri = new URI(request.getRequestLine().getUri());
        String encodedParams = uri.getRawQuery();

        String decoded = URLDecoder.decode(encodedParams, "UTF-8");
        //parse query string in a map
        Map<String, String> query = getQueryMap(decoded);
        ParameterList requestParams = new ParameterList(query);
        Message openidResp = openidManager.authResponse(requestParams, null,
null, false, true);
    }

will generate:
Exception in thread "main" java.lang.NullPointerException
