I tried to setup Cofoja in my eclipse project as described here. When I try to run my project with Cofoja I always get an IllegalArgumentException.
[com.google.java.contract:agent FATAL ERROR while instrumenting cofoja/Main (stack trace follows)]

I have no idea what I did wrong with my setup or where the problem resides... And I'm also not sure whether to use Cofoja in a long-term project or not as it doesn't look very active to me. What is your thought on that?
I just got it working by compiling Cofoja myself. I think there might be a problem with java 8 and the provided jar files.
