NoClassDefFoundError creating a dashboard

[misterstrickland]

I've been using the environment dashboard in Jenkins for a few months now. One day I logged in and my dashboard (I only had one) was totally gone!

I tried recreating it but I hit a NoClassDefFoundError:

I tried removing and reinstalling the plug-in, but no luck... The stack trace above is all that jenkins.log shows.

The contents of my environment dashboard plugin folder can be found below. Any ideas?
