getServletPath() output JSP name instead of action name when a request is forwarded inside Servlet application in EAP 7

Issue

We are trying to migrate our application from JBoss EAP 6.x to JBoss EAP 7.x. We found that EAP 6.x and EAP 7.x return different results of HttpServletRequest.getServletPath() (and also getRequestURI() and getRequestURL()](https://docs.oracle.com/javaee/7/api/javax/servlet/http/HttpServletRequest.html#getRequestURL--)) after invoking RequestDispatcher.forward(). This behavior change causes an issue with our application using Struts and Siteminder framework.

• In JBoss EAP 6.4:

  getServletPath() = /example.action 
  getRequestURI() = /myapp/example.action
  

• In JBoss EAP 7.x:

  getServletPath() = /jsp/forward/example.jsp 
  getRequestURI() = /myapp/jsp/forward/example.jsp 
  

Also, you can observe the different behavior with the following code in the servlet application without using Struts framework:

System.out.println("getServletPath() before forward = " + request.getServletPath());
System.out.println("getRequestURI() before forward = " + request.getRequestURI());
System.out.println("getRequestURL() before forward = " + request.getRequestURL());
request.getRequestDispatcher("/jsp/forward/example.jsp").forward(request, response);
System.out.println("getServletPath() after forward = " + request.getServletPath());
System.out.println("getRequestURI() after forward = " + request.getRequestURI());
System.out.println("getRequestURL() after forward = " + request.getRequestURL());

• In JBoss EAP 6.4:

  getServletPath() before forward = /example
  getRequestURI() before forward = /myapp/example
  getRequestURL() before forward = http://<hostname>:<port>/myapp/example
  getServletPath() after forward = /example 
  getRequestURI() after forward = /myapp/example
  getRequestURL() after forward = http://<hostname>:<port>/myapp/example
  

• In JBoss EAP 7.x:

  getServletPath() before forward = /example 
  getRequestURI() before forward = /myapp/example
  getRequestURL() before forward = http://<hostname>:<port>/myapp/example
  getServletPath() after forward = /jsp/forward/example.jsp 
  getRequestURI() after forward = /myapp/jsp/forward/example.jsp 
  getRequestURL() after forward = http://<hostname>:<port>/myapp/jsp/forward/example.jsp
  

Is it possible to make JBoss EAP 7 behave the same as JBoss EAP 6?
