          Bug - A problem that impairs or prevents the functions of the product. UNDERTOW-2245 javax.servlet.*.mapping request attributes are not available in servlets forwarded with RequestDispatcher

          • 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.
