Hi guys,

I'm running 0.7.4 of the Violations plugin. After upgrading to 1.319 of Hudson,
my builds began to fail with the following message:

The builds are successful when I revert Hudson to version 1.318.

Looking at the location of the NPE, it looks like that class hasn't been changed
for months:
