My team is also having the same issues. I attempted to follow the steps here (
http://khengineering.github.io/RoboRio/faq/java/), however when I do go to usr/local/frc/JRE/bin, I don't know which one is the jar file since it doesn't say if it is a jar file. (I see java, keytool, rmind, and rmiregistry)
We were previously able to get code working last week, but then this problem popped up this week. I've tried updating the firmware and re-imaging, but it didn't work.
Unfortunately, my team's programmer left last year, so we're back to being rookies in terms of programming. So, that means I have no idea what this means. Not sure if it'll help, but here's my log (the error is also bolded):
