  Exception in AppMerge flows' progression
  VALIDATION PROBLEMS WERE FOUND problem: cvc-complex-type.2.4b: Element not allowed: tracking-mode@http://java.sun.com/xml/ns/javaee in element session-config@http://java.sun.com/xml/ns/javaee:&lt;null&gt;

  <p>How to solve this? It would be good also a way in order to skip validation.</p>
  
  <p>The server log reports the following message:</p>
