When Confluence is used with Websphere 6.1.0.5 resources such as CSS and Javascript are not loaded correctly resulting in unstyled content and javascript errors.

From Anton on JRA-12039: The problem is that WebSphere 6.1.0.5 checks if a URL is mapped to a servlet or a file before it puts a request through the filter chain.

This means our resource requests totally miss the URL rewriting filter, breaking the loading of JS and CSS resources.
