GenericWebApplicationContext now implements ConfigurableWebApplicationContext in order to be compatible with Framework/DispatcherServlet and ContextLoader/Listener, especially with regard to changes in SPR-7672 that allow for programmatic use of these types within Servlet 3.0+ environments. For the first time, it's now reasonable to imagine injecting a GWAC into DispatcherServlet; the most robust way to accommodate this possibility is for GWAC to implement CWAC. The implementation is in name only, allowing for interchangable use of GWAC anywhere, for example, an XWAC could otherwise go. Methods such as setConfigLocation will throw UnsupportedOperationException if the configLocation value actually contains text. Other methods are implemented as no-ops or to throw UOE as appropriate.
