Thanks @pzygielo for having a look and adding some testing. As far as I am aware we do not use plain asserts so please use JUnit helper methods instead. There is the bigger question if instead of extracting a method to provide full generic type we add the generics to the field instead as it seems to be expected a fix type everywhere anyway. If you feel confident making that change please go ahead and do that.

@jbee - thanks Jan for checking. I will rebase and update tests.
I'd be happy to check
