Major Description
If an application uses <wicket:link> to generate a url for a static resource, e.g.
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:wicket="http://wicket.apache.org/"> <head> <wicket:head> <wicket:link> <link rel="stylesheet" type="text/css" href="css/test2.css" /> </wicket:link> </wicket:head> </head> ...
then during the page render time it will use
CharSequence url = getRequestCycle().urlFor(handler);
and https://github.com/apache/wicket/blob/bc70f127ff74f154890a35be906b55db5bdc8683/wicket-core/src/main/java/org/apache/wicket/request/resource/PackageResourceReference.java#L117-L128 will use the current page's url and try to parse locale/style/variation from it and embed it in the static resource url.
The problem is that it uses the pageId/renderCount/behaviorId and component path instead.
