 Error "Unexpected exception executing action org.drools.reteoo.PropagationQueuingNode$PropagateAction at 631b86c7" with two after-clauses
---------------------------------------------------------------------------------------------------------------------------------------

                 Key: JBRULES-2957
                 URL: https://issues.jboss.org/browse/JBRULES-2957
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-core (fusion)
    Affects Versions: 5.1.1.FINAL
         Environment: macosx snowleopard jdk 1.6.x
            Reporter: Armin Steudte
            Assignee: Mark Proctor


I'm getting the following Error "Unexpected exception executing action org.drools.reteoo.PropagationQueuingNode$PropagateAction at 631b86c7" with one off my rules in my project. 
The problem is linked with the use of two after statements in one rule. 
If I delete one of them everything works like a charm. 
The rule looks like this: 

// Regeln 
rule "Vergessene Herdplatte" 

    when 
        // Platte wurde eingeschaltet und es steht kein Topf auf ihr 
        $platte: HerdplatteEingeschaltet( plateOccupied == false ) from entry-point events 
        // und in den nächsten 20 sek wird die gleiche Platte nicht ausgeschaltet 
        not( HerdplatteAusgeschaltet( this.nummer == $platte.nummer, this after[0s,20s] $platte ) from entry-point events ) 
        // oder es wird in den nächsten 20 sek kein Topf auf die Platte gestellt 
        not( TopfAufHerdplatte( this.nummer == $platte.nummer, this after[0s,20s] $platte ) from entry-point events ) 
    then 
        System.out.println("Vergessene Herdplatte erkannt!"); 
    
end 

If I comment one of the not-clause out, it works. 
I created an unit-test which reproduces the exception. 
And here the Failure Trace:
