Not sure but here's my best guess:
Upon container shutdown, Spring (or maybe the container itself) tries to be a good citizen and serialize the session to disk. Now there are some components/classes in flowscript that are not serializable, hence the session serialization fails and you get this stacktrace.

Hi,
When I shut down my tomcat server with my cocoon application (schaman) inside, I get a mysterious NotSerializableException which seems to be linked to both Spring and Flow (see org.mozilla.javascript.NativeJavaObject.writeExternal(NativeJavaObject.java:993)) :

Any idea of what can be the cause of that ?
Thx in advance.
