Small '?' Bug in JBoss AS 4.0.4.CR2

There is a small bug in this version that wasn't there in 4.0.3SP1.

If you were to type a path to a servlet, for example the jmx-console, with a backslash at the end:
http://localhost:8080/jmx-console/
Nothing goes wrong. If you entered:
http://localhost:8080/jmx-console
The browser (for me it's Firefox) will display it as:
http://localhost:8080/jmx-console/?

Functionality-wise nothing changes, but the '?' is sorta weird, if not irritating.

I do not know if it is reproducible in other computers, but it is definitely reproducible on mine. I'm using JDK1.5.0_06 in Windows XP SP2. I've tried the manual self-install package and it reappears everytime for the default configuration. For the installer, I tried the ejb3 configuration and it appears too.
