Hi. I'm getting this trying to read a serialized drools session (java 7, drools 5.1.1): Caused by: java.lang.ClassCastException: org.drools.reteoo.RuleTerminalNode cannot be cast to org.drools.reteoo.RightTupleSink at org.drools.marshalling.impl.InputMarshaller.readRightTuple(InputMarshaller.java:401) [drools-core.jar:5.1.1] at org.drools.marshalling.impl.InputMarshaller.readRightTuples(InputMarshaller.java:391) [drools-core.jar:5.1.1] at org.drools.marshalling.impl.InputMarshaller.readFactHandles(InputMarshaller.java:326) [drools-core.jar:5.1.1] at org.drools.marshalling.impl.InputMarshaller.readSession(InputMarshaller.java:205) [drools-core.jar:5.1.1] at org.drools.marshalling.impl.DefaultMarshaller.unmarshall(DefaultMarshaller.java:91) [drools-core.jar:5.1.1] this happens when trying to deserialize using Marshaller.unmarshal(). is this a known (hopefully fixed?) issue with 5.1.1 ? is it possible im doing something wrong? -- View this message in context: http://drools.46999.n3.nabble.com/ClassCastException-trying-to-deserializ...
