I was configuring a windows developer environment on my new laptop until
the new Ubuntu LTS is released when I saw your problem. I've downloaded and
tested your application with:

* Windows 7 x64
* Latest Java 1.7
* Maven 3.0.4

I can reproduce the problem from cli but I can't import the project into
Eclipse so I didn't investigate further. The sitemap.xmap looks fine so I
have to test the samples block for C3 to check if it's a common problem.

Lars, did you tested the samples block yet? is it working for you?
Thorsten, did you tested the Lars sample in Linux?

Lars, to be easier to download your sample I think that is better if you do
a "mvn clean" first to avoid all the  maven generated stuff also if you
create a .zip file with all the stuff it could be better.
