"not" doesn't work for StatelessSessions
----------------------------------------

                 Key: JBRULES-1116
                 URL: http://jira.jboss.com/jira/browse/JBRULES-1116
             Project: JBoss Rules
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions:  4.0.0.GA
            Reporter: Dean Jones
         Assigned To: Mark Proctor
            Priority: Blocker


When using a StatelessSession, the "not" quantifier doesn't work. Test case below.

package org.drools.examples

rule "Hello World"
       when
           Integer()
       then
           System.out.println("Hello world");
end

rule "Goodbye World"
       when
           not Integer()
       then
           System.out.println("Goodbye cruel world");
end

public class TestReadRuleFile {

 public static void main(String[] args) throws Exception {
  PackageBuilder builder = new PackageBuilder();
  InputStreamReader is = new InputStreamReader(
   TestReadRuleFile.class.getResourceAsStream("test.drl"));
  builder.addPackageFromDrl(is);
  Package pkg = builder.getPackage();
  RuleBase jbossRulebase = RuleBaseFactory.newRuleBase();
  jbossRulebase.addPackage(pkg);
  StatelessSession session = jbossRulebase.newStatelessSession();
  session.execute(new Float(1));
 }

}

The "Goodbye world" rule should fire (there are no Integers in the working memory) but doesn't. If you switch to a StatefulSession, the "Goodbye world" rule does fire.
