    Description

      Given a servlet registered to "/" and ".ext", requests which attempt to read getHttpServletMapping result in StringIndexOutOfBoundsException attempting to substring an empty string.
      The problem is the current implementation expects the matched portion to match the uri, however it doesn't contain the trailing component when an extension is matched.

      Caused by: java.lang.StringIndexOutOfBoundsException: begin 0, end -5, length 0

          Bug - A problem that impairs or prevents the functions of the product. UNDERTOW-1866 NPE in HttpServletRequest#getHttpServletMapping()

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
