MyFaces implementation of JSF2.1 had org.apache.myfaces.SERIALIZE_STATE_IN_SESSION default to true, wheres Mojarra had com.sun.faces.serializeServerState default to false.

From JSF2.2 onwards this will be standardised via javax.faces.SERIALIZE_SERVER_STATE which defaults to false.

    javax.faces.SERIALIZE_SERVER_STATE
    true
