>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>    Affects Versions: 5.1.0.FINAL
>         Environment: Windows Server, SQL Server 2005, Tomcat 5.5, Hibernate, Bitronix

> After an event is processed the session fails to load using JPA persistence.
> I ve attached a test case.
> It uses a Drools flow file, and a drl file. Both very simple..
> The flow file has a "Start" then an action that prints a message to the console, then "End"
> The Drl has one rule that processes an event:
> import com.kgcontrols.services.company.standardsRequests.workflow.events.VoteCreatedEvent
> declare VoteCreatedEvent
>        @role(event)
> end
> rule "testEvents"
>        when
>                VoteCreatedEvent() from entry-point "VoteCreatedStream"
>        then
>                System.out.println("--------------------------- YEAH the event got here");
> end
> I can see the "YEAH the event go here" on the console so I know the rule fired. But after that, if I try to load the session from the database I get:
