Vaadin session serialization in Wildfly cluster

We have problem in Wildfly Cluster enviroment. It fails if serialization happens when there is Vaadin Window on session.

This are steps to repreduce:

When redeploy happend session was serialized sucessfuly. But when deserialzation happens it fails with error (stactrace attached).

Does anyone have experiance with using Vaadin in cluster enviorment and Vaadin session serialization, especially with Wildfly cluster?
