putting Selenium Code into CrawlController --> Exception in thread "main" java.lang.NoSuchFieldError: INSTANCE

[GoogleCodeExporter]

I´m using Eclipse and Java for configuring my Crawler (Crawler4j)
- Crawler4j works alone as I wish and crawls my Sites properly.
- Selenium in own main class works as I wish and opens Firefox.

What steps will reproduce the problem?
1.Putting WebDriver driver = new FirefoxDriver(); into my CrawlController (into 
the main())
2.Putting WebDriver driver = new FirefoxDriver(); into  public void visit(Page 
page) {.....} of my public class MyCrawler extends WebCrawler {...}

What is the expected output? What do you see instead?
The Crawler should get information like Id´s of the page and handle them to 
Selenium for testing.

What version of the product are you using?
- Crawler4j 3.5 jar
- Selenium-java-2.42.jar

Please provide any additional information below.
Here the Exception I get when putting the Selenium code with the 
CrawlController:

I don't think it works like you think. the webcrawler doesn't run in a browser 
like you are telling selenium to do. You can try creating the selenium instance 
where you start crawlers. then pass that to the crawl process that contains 
visit(Page page) method.

What are you trying to do exactly?

Hi, it works now it was just an old httpclient.jar and httpcore.jar that causes 
that issue. I can crawl the site get the Source by the crawler then parse the 
source and then pass it to selenium to work further.
