I'm running application on Wildfly managed domain that consists from 2 virtual machines with 3 servers on each VM.
Exception occurs in console.log:

I've trying to run application on wildfly 8.2.1.Final and 9.0.2 Final with openjdk-1.8 and Oracle jdk-1.8 with same result. Application deployed and running with no errors, I'm successfully login and working on servers through load balancer (round robin).
In undertow sources at github field hashCode of class io.undertow.util.HttpString declared as final transient int. Why readObject method trying to change value of this field by very strange way?
I have googled the Internet but found nothing about this or similar error and do not know what to do with it.
Where may be the place in my application which belongs to this exeption?
Update: This patch for Undertow server helps me to avoid problem:
