Wicket application throws IllegalStateException when bound to multiple JBoss virtual hosts

Issue

• Our application using wicket is bound to two virtual hosts in its WEB-INF/jboss-web.xml:

  <virtual-host>externalhost</virtual-host>
  <virtual-host>localhost</virtual-host>
  

  When the application is deployed, we see the following IllegalStateException:

  ERROR [org.apache.wicket.protocol.http.WicketFilter] (main) The initialization of an application with name 'helloworld' has failed.
  java.lang.IllegalStateException: Application with name 'helloworld' already exists.'
