As mentioned, serialization is not supported for script objects to avoid
security, versioning issues (i.e,freely evolving internal implementation
data structures). But, it should be possible to "serialize" a required
global variables as a JSON document (JSON.stringify accepts "replacer"
function which can be used to customize - for example, java serializable
object values of global vars can be serialized and encoded as needed).
JSON.parse can be used to "deserialize" - again "reviver" function can
be used customize deserialization of particular values.
Hope this helps,
