------------------------------------------
Nope, this modification is supposed to be resolve classes whose URLs are
different from those Tapestry is able to resolve. That's all. ModuleDef on its
part is responsible for embedding services into Tapestry that are binded
outside the AppModule. Since in OSGi we also have a bunch of service we may
contribute the OSGi services to Tapestry by using the ModuleDefs.

> ClassNameLocatorImpl is only able to resolve resources from URLs that use a
> protocol which is native to the Java class library (file, jar, http, etc). In
> OSGi environment all the URLs use the protocol "bundleresource" or
> "bundleentry". Here is an example:
> bundleresource://5642/org/apache/tapestry5/corelib/pages/
> A very simple solution is to create your own ClassNameLocator and contribute
> it to AliasOverrides. Well, this solution is bad because it requires a copy
> of the ClassNameLocatorImpl.
> A better solution would be to make ClassNameLocatorImpl use a service called
> URLConverter or similar.
> public interface URLConverter
> {
> URL convert(URL url);
> }
> Tapestry would provide a default implementation of the interface:
> public class URLConverterImpl implements URLConverter
> {
> public URL convert(URL url)
> {
> return url;
> }
> }
> In an OSGi environment (in my case Equinox) one could override this service
> by using e.g Eclipse Core API. This approach is much easier then overriding
> of the ClassNameLocator.
