Description

When using HTTP session persistence and replication the web server needs to serialise and deserialise the objects stored into the session map.
It turns out that org.icefaces.impl.application.WindowScopeManager class has a static field that is deserialised, but the field is not Serializable or Externalizable.
Static fields are never serialised but they can be deserialised if the filed is initialised while the class loads.

org.icefaces.impl.application.WindowScopeManager instances are not stored in the session and thus NotSerializableException shouldn't occur. Unfortunately the instances of the inner class org.icefaces.impl.application.WindowScopeManager.State are stored into the session. During object deserialisation the outer class needs to be loaded as well which triggers NotSerializableException when deserialising the static non-serialisable field.

Here's a detailed explanation for the reason why and when static fields are deserialised: https://javabeginnerstutorial.com/core-java-tutorial/transient-vs-static-variable-java/
