Martin Grigorov commented on WICKET-4803:
-----------------------------------------
I'm not sure Wicket can do something about this.
Issuing http://localhost:8080/%%%% (not the missing '?') leads to :
java.lang.NumberFormatException: %%

i.e. again error 500.
The only way to show a Wicket page as a handler is to add:
<error-page>
<error-code>500</error-code>
<location>/error</location>
</error-page>
to web.xml and
#mountPage("error", getApplicationSettings().getInternalErrorPage());

> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.5.8, 6.5.0
> Reporter: Johan Heylen
> Assignee: Martin Grigorov

> In the class: org.apache.wicket.protocol.http.WicketURLDecoder there are two
> IllegalArgumentException which should be wrapped in WicketRuntimeException,
> otherwise they are caught by the exception handler form the servlet container
> (jetty, tomcat, ...) which then uses their http 500 error code configuration
> instead of the exception handling of wicket.
> Wrapping them would be good for consistency and help manage runtime
> exceptions.
> These are the two exceptions:
> throw new IllegalArgumentException("URLDecoder: Incomplete trailing escape
> (%) pattern");
> throw new IllegalArgumentException("URLDecoder: Illegal hex characters in
> escape (%) pattern - " + e.getMessage());
