> When trying to marshall and then unmarshall a StatefulKnowledgeSession where a Fact has been inserted into an entry-point a NullPointerException is thrown:
> java.lang.NullPointerException
> at org.drools.reteoo.RuleTerminalNodeLeftTuple.<init>(RuleTerminalNodeLeftTuple.java:151)
> at org.drools.reteoo.RuleTerminalNode.createLeftTuple(RuleTerminalNode.java:608)
> at org.drools.marshalling.impl.InputMarshaller.readLeftTuple(InputMarshaller.java:523)
> at org.drools.marshalling.impl.InputMarshaller.readFactHandles(InputMarshaller.java:373)

> Provided is a testcase with two simple rules matching Fact objects directly and from the entry-point "facts".
> A fact is inserted directly into the knowledgeSession and then it is marshalled and unmarshalled - which works fine.
> Then a fact is inserted into a entry-point "facts" and the session is marshalled and unmarshalled - which throws the NPE.
