Solrj - cannot inherit from final class error due to HTTPSolrServer

I have been using Solr version 4.10.2. I added solrj version 4.10.2 by using maven (pom.xml) 

<dependency>
    <groupId>org.apache.solr</groupId>
    <artifactId>solr-solrj</artifactId>
    <version>4.10.2</version>
        <scope>compile</scope>
</dependency>

These are maven dependencies that are installed: 

solr-solrj-4.10.2.jar
httpclient-4.3.1.jar
httpcore-4.3.jar
httpmime-4.3.1.jar
wstx-asl-3.2.7.jar
wstx-asl-3.2.7.jar
noggit-0.5.jar

When I define solr http path, l get and exception: 

Exception in thread "main" java.lang.VerifyError: Cannot inherit from final class

    at addIndex.main(addIndex.java:10)

This is how I define solr path:

HttpSolrServer server = new HttpSolrServer("http://localhost:8983/solr"); or 

HttpSolrServer server = new HttpSolrServer("http://localhost:8983/solr/#/collection1");

Is there another way to make a connection with java project? What is the reason that I get this exception?

If you're connecting to Solr (and using SolrJ as the client library), you're supposed to instantiate HttpSolrClient:

String urlString = "http://localhost:8983/solr/collection1";
SolrClient solr = new HttpSolrClient(urlString);

BTW: Anchors in URLs (such as #foo) is meant for clients only (such as browsers), and are not meant to be (and thus, isn't, usually) transmitted as part of the request.
