After updating to the latest Warning plugin, 2.10, and using Hudson 1.314,
whenever I attempt to enable the Warnings plugin for a Job, an exception is
generated when I click "Save" from the configuration screen of the Job. I can
save the same job with the Warnings plugin un-checked successfully. But it I try
to enable it, I always get the same exception. This happens even for a brand new
project.

The exception is below. Here I list other Job settings if it helps:

• Name/Description filled
• CVS with a few modules
• Polling SCM
• Email notification
• Status Monitor
