If it's critical to fix it fast, you could remove the super.destroy() call
to prevent the exception.
It sounds like the GenericServlet doesn't have a servlet context. The
GenericServlet.destroy() method calls the ServletContext.log() method. You
could always not call the super.destroy() to avoid the error, but you
should investigate why your getServletContext() returns null. Make sure
that the ServletConfig passed in during init is not null and that the
ServletConfig.getServletContext() does not return null. Also make sure
that your servlet calls super.init(config).
