Sorry, here's the stack trace:

I'm thinking it isn't important, but just in case, here is the rule as well.
rule "CheckCounter"
   salience 65500
   dialect "mvel"
   when
      not ($xev:XEVCounter())
   then
      XEVCounter newone = new XEVCounter();
      newone.setCount(new java.util.concurrent.atomic.AtomicLong(0));
      insert(newone);
      // a comment
end

declare XEVCounter
   count:java.util.concurrent.atomic.AtomicLong
end
