Actually, what's causing this is that before september 13th, when the session was marshalled, no initialFactNode was retrieved and marshalled -- and now that _is_ happening. 

The following code is from the OutputMarshaller class: 
{code}
    public static void writeInitialFactHandleRightTuples(MarshallerWriteContext context) throws IOException {
        ObjectOutputStream stream = context.stream;
        InternalRuleBase ruleBase = context.ruleBase;

        ObjectTypeNode initialFactNode = ruleBase.getRete().getEntryPointNode( EntryPoint.DEFAULT ).getObjectTypeNodes().get( ClassObjectType.InitialFact_ObjectType );

        // do we write the fact to the objecttypenode memory
        if ( initialFactNode != null ) {  // <-- this if clause was not entered before! 
{code}

> The org.drools.persistence.session.ReloadSessionTest fails at the moment. 
> I'm seeing a npe thrown here:  
> {code}
> ConcurrentNodeMemories.getNodeMemory(NodeMemory) line: 65	
> ReteooStatefulSession(AbstractWorkingMemory).getNodeMemory(NodeMemory) line: 1040	
> InputMarshaller.readFactHandles(MarshallerReaderContext) line: 373	
> InputMarshaller.readSession(MarshallerReaderContext, int, ExecutorService, Environment, SessionConfiguration) line: 255	
> DefaultMarshaller.unmarshall(InputStream, KnowledgeSessionConfiguration, Environment) line: 92	
> SessionMarshallingHelper.loadSnapshot(byte[], StatefulKnowledgeSession) line: 91	
> SingleSessionCommandService.initKsession(Integer, KnowledgeBase, KnowledgeSessionConfiguration) line: 221	
> {code}
> The cause of this seems to be that when InputMarshaller.readFactHandles(MarshallerReaderContext) runs in this test, the sinkId retrieved from the stream is _6_, but should be 2. The context contains an ObjectTypeNode with id 2, but not 6, in other words (and id 2 maps correctly).
> When I change the value (during debugging) to 2, the test completes successfully.
