    This problem seems to happen because the Spring framework is
    doing a direct reference to our SimpleFileServlet. This is not
    allowed and not supported.
    

Local fix

  • I have seen reports of people fixing this by setting Spring not
    to handle static file requests, but I haven't tested this
    solution so I am not sure of it solves the issue. Just wanted
    to throw that idea out there for the customer to try.
