Steps to reproduce:

1. Download apache-solr-3.5.0.zip from 'http://archive.apache.org/dist/lucene/solr/3.5.0/'
2. Unzip apache-solr-3.5.0.zip anywhere
3. Navigate to apache-solr-3.5.0/example in terminal and type 'java -jar start.jar'
4. After the server has started up, shut it down
5. Start Liferay and deploy the Solr3 plugin
6. After it's started, shut it down
7. Navigate in folder to /tomcat-7.0.42/webapps/solr3-web/WEB-INF/classes/META-INF
8. Open solr-spring.xml
9. Change 'http://localhost:8080/solr' to 'http://localhost:8983/solr'
10. The changed line should look like this: <constructor-arg type="java.lang.String" value="http://localhost:8983/solr/" />
11. Save and close solr-spring.xml
12. Navigate in folder to /tomcat-7.0.42/webapps/solr3-web/WEB-INF/conf
13. Copy the schema.xml file
14. Paste the file in apache-solr-3.5.0/example/solr/conf to replace the existing schema.xml file
15. Start the Solr3 server in apache-solr-3.5.0/example (java -jar start.jar)
16. Start liferay
17. There will be a lot of outut on the Solr3 console (means it's working)
18. Navigate to Control Panel > Server Administration and reindex spellcheck

Expected result:
Reindexing should complete without any errors in liferay terminal.

Actual result:
Liferay terminal returns errors:
