java.lang.ClassCastException

[sdeanHarris]

My stuff was working last week fine and then I rebooted my box and tried to run everything. I am getting the following error and not sure how to debug or even know what is broken. If I build my project from command line and run outside of Eclipse everything is ok. Any ideas or help would be great.
