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.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!
