      The list of routes is changed without proper synchronization. One example, I got an empty list when in Infinispan when try to select the route to use:

      Caused by: java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

      One possible solution is to do a copy of the list before changing it in the view change method invocation (for the bridge)
