How can I mount a Wicket application at /* in GAE development server?

My Wicket application runs fine on the live Google App Engine at /*

<filter-mapping>
    <filter-name>WicketApplication</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

However this URL pattern does not work on the development server (GAE 1.2.8): a request 开发者_如何学编程to http://localhost:8080/ gives this message:

HTTP ERROR: 500

INTERNAL_SERVER_ERROR

RequestURI=/
Caused by:

java.lang.StackOverflowError
    at java.lang.String.startsWith(String.java:1451)
    at org.mortbay.jetty.servlet.Dispatcher$ForwardAttributes.setAttribute(Dispatcher.java:365)

    at org.mortbay.jetty.servlet.Dispatcher$ForwardAttributes.setAttribute(Dispatcher.java:379)
    at org.mortbay.jetty.servlet.Dispatcher$ForwardAttributes.removeAttribute(Dispatcher.java:399)
...

There are no other servlets in the web.xml which could interfere, so maybe it is a known problem?

I had similar kind of problem in OC4J, look at my solution here.
