why do I get 404?

[T <rl...@bonbon.net>]

If I have these two lines in a jsp:

<%! String loginLink = ("login.jsp"); %>
<%! String advLink = ("users/adv_scanner.jsp"); %>

then 3.2.1 gives me a 404 (not a 500) when I try to access the page.
How can that be?

If I eliminate *either* line, one at a time, then there is no problem.
