Lines 1 to 28 in cabccb1

	package org.orienteer.oposter.ok;
	import com.github.scribejava.apis.OdnoklassnikiApi;

	public class FixedOdnoklassnikiApi extends OdnoklassnikiApi {
	private static class InstanceHolder {
	private static final FixedOdnoklassnikiApi INSTANCE = new FixedOdnoklassnikiApi();
	}
	public static FixedOdnoklassnikiApi instance() {
	return InstanceHolder.INSTANCE;
	}
	@Override
	public OdnoklassnikiOAuthService createService(String apiKey, String apiSecret, String callback,
	String defaultScope, String responseType, String userAgent, HttpClientConfig httpClientConfig,
	HttpClient httpClient) {
	return new FixedOdnoklassnikiOAuthService(this, apiKey, apiSecret, callback, defaultScope, responseType, userAgent,

	}
	}

Maybe it could be solved like this
