Error unmarshalling knowledgeSession with Facts inserted in entry-points ------------------------------------------------------------------------ Key: JBRULES-3222 URL: https://issues.jboss.org/browse/JBRULES-3222 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-core Affects Versions: 5.2.0.Final, 5.3.0.Beta1 Reporter: Stefan Wehner Assignee: Mark Proctor Labels: entry-point, marshall, npe, unmarshall Fix For: 5.3.0.Final Attachments: persist_testcase.tgz 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) at org.drools.marshalling.impl.InputMarshaller.readSession(InputMarshaller.java:230) at org.drools.marshalling.impl.DefaultMarshaller.unmarshall(DefaultMarshaller.java:92) at org.drools.marshalling.impl.DefaultMarshaller.unmarshall(DefaultMarshaller.java:63) at com.sample.DroolsTest.main(DroolsTest.java:50) 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.
