I'll probably leave it as Strings. I'll also look at the Filter mapping code. However, the entire point of the exercise is that we *don't* have to test all of the security-constraints. If I have a security-constriaint with a <url-pattern>/protected/*</url-pattern>, and another one with <url-pattern>*.jsp</url-pattern>, then for a request to /myapp/protected/index.jsp, only the first constraint is checked.
