Finding subtypes of a class does not work if intermediate types in the hierarchy are not in the search url

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create class A in a url "url1"
2. Create class B, where B extends A, in a url "url2"
3. Create class C, where C extends B, in a url "url3".
4. Find the set of subtypes of class A in "url3" with the following code:

ConfigurationBuilder config = new ConfigurationBuilder();
config.addUrls(url3);
Reflections reflections = new Reflections(config);
Set<Class<? extends A>> set = reflections.getSubTypesOf(A.class)
System.out.println(set);

What is the expected output? What do you see instead?
The expected output is class C. However, an empty set is shown instead.

What version of the product are you using? On what operating system?
0.9.8, OSX Lion.

Please provide any additional information below.
I do not know in advance the url of all the intermediate classes in the class 
hierarchy (in the example, only B is between A and C, but they could be more 
classes of course). Currently I need to ask the users of my library to 
explicitly add those urls. But since the class that should be found is in the 
filtered url, and the predicate over it holds (C is indeed a transitive 
subclass of A), I would have expected it to be found without any additional 
settings.
If there are no plans to change this behavior any pointer to how I could extend 
Reflections to do this would be highly appreciated.

choose your urls carefully, know your classpath. otherwise scan everything! 
(ClasspathHelper.forClassLoader(<noarg>))

Unfortunately, I was not able to scan everything with reflections. 

What would the code look like? I only managed to scan  by providing the first 
part of a package (i.e. "com" or "info").

just new Reflections() with the trunk snapshot version
than the urls are effectively ClasspathHelper.forClassLoader()

I see. I was using 0.9.8 at the moment.
Is there a simple way to do it with 0.9.8 aswell?

on 0.9.8 use new Reflections(ClasspathHelper.forClassLoader())

Thank you. This seems to work, but unfortunately, my tests won't run anymore, 
as the surfire maven plugin seems to load its classes from somewhere else. 

I managed to get it running using 
.setUrls(ClasspathHelper.forPackage("", ClasspathHelper.classLoaders()))

Not sure why this works. 

Do you have an example of a junit test?
Maybe I should aks there questions somewhere else... Where?

Thanks
