Can't execute rules twice with a second classloader
---------------------------------------------------

                 Key: JBRULES-1009
                 URL: http://jira.jboss.com/jira/browse/JBRULES-1009
             Project: JBoss Rules
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Reteoo
    Affects Versions:  4.0.0.MR3
            Reporter: aaron dixon
         Assigned To: Mark Proctor
            Priority: Minor
         Attachments: drools-test.zip

I am trying to sequentially perform two rules executions using two
different classloaders in the same VM. I create completely new state
for each execution, yet I still fail on the second execution (the first execution succeeds). I
believe this has to do with some internal static cached state that
JBossRules is maintaining. An integration test is attached as an archived Eclipse project (zip).

Exception thrown:
