[rules-users] Marshalling/Unmarshalling of KieSession

Dear all, I've to questions concerning the marshalling and unmarshalling of KieSessions. First, is there any detailed documentation on the ObjectMarshallingStrategy interface? I am quite confused about the purpose of the write and read methods in the interface. In my implementation they are never called. Are they deprecated or under which circumstances are they called by the implementation? My second question is about the relationship of the KieSession, KieBase and the KieContainer in case of marshalling/unmarshalling. Assume that I create a KieSession based on a KieBase that is created from a KieContainer based on a release X. When marshalling this session, is there any information marshalled about which release this session is based upon? I am asking since when I unmarshall the session I want to ensure to initialize the unmarshaller based on a KieBase with the same release X as the marshalled version of the session. Do I have to store this information out of band or what's the recommended way to implement this? Thanks, Ingo
