Add Random Extra params=true causes java.lang.IndexOutOfBoundsException

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Using jar built from trunk, run 'java -jar 
solrmeter-0.1.2-SNAPSHOT-jar-with-dependencies.jar'
2. In SolrMeter application menu bar, click edit then select settings.
3. Change "Add Random Extra Params" to 'true'
4. Click Apply then OK
5. In "Query Console" click start button. 
6. Watch the console output for the IndexOutOfBoundsException.

What is the expected output? What do you see instead?
I expect to see queries from SolrMeter in my Solr log, real time changes to the 
Historgram or Pie chart or Query Time History.

What version of the product are you using? On what operating system?
Solrmeter Revision 167 on Ubuntu 10.04.1

Please provide any additional information below.
When this is set to false, queries are sent to solr as expected.
