> 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).
