[rules-users] Error when trying to serialize session

[dmiller44]

I'm getting the following stack when trying to serialize a session containing
one running process:

java.io.NotSerializableException:
org.drools.workflow.instance.impl.NodeInstanceFactoryRegistry
	at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1156)
	at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:326)

	at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:326)


The call is thrown from this line of code:

droolsOut.writeObject(session.getKnowledgeBase());


Is this a legitimate bug in Drools?  Or is this because something in my
knowledge base is not serializable?  The
"org.drools.workflow.instance.impl.NodeInstanceFactoryRegistry" is what is
confusing me if this is my issue or a Drools issue. 

Thanks!
