  ****************************************************************
  A call to javax.servlet.AsyncContext.dispatch() might dispatch
  to the original URI instead of the new dispatched URI which is
  the result of
  javax.servlet.http.HttpServletRequest.getRequestURI().
  

Problem conclusion

• The WebContainer code was modified to dispatch to the correct
  URI when a new WebContainer custom property is set.
  
  
  A new WebContainer custom property needs to be set to enable
  this behavior:
  
  Name:
  com.ibm.ws.webcontainer.setAsyncDispatchRequestURI
  
  Values: true / false (default)
  
  
  Please refer to the following technote for instructions on
  enabling WebContainer custom properties:
