file:// protocol URL might not work with 3rd party libraries

A URL like this

file:/home/tdiesler/svn/jboss-osgi/trunk/testsuite/example/target/test-libs/example-http.jar/res/message.txt

gets passed to a 3rd party library (i.e. Jetty)

which does stuff like this

public static Resource newResource(URL url, boolean useCaches)
{
if (url==null)
return null;

String url_string=url.toExternalForm();
if( url_string.startsWith( "file:"))
{
try

{ FileResource fileResource= new FileResource(url); return fileResource; }

catch(Exception e)

{ Log.debug(Log.EXCEPTION,e); return new BadResource(url,e.toString()); }

}
else if( url_string.startsWith( "jar:file:"))

{ return new JarFileResource(url, useCaches); }

else if( url_string.startsWith( "jar:"))

{ return new JarResource(url, useCaches); }

return new URLResource(url,null,useCaches);
}

As a consequence, content access does not work.

This seems to be a general issue caused by the reuse of the well known file:// protocol which may be processed explicitly by 3rd party libs.
