      Description

      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:

      --------------------------- YEAH the event got here
