hmm, I think you missed the point that we start with lower admin_levels:
        // Reverse the sorting because we want to start with the lowest admin level
        Collections.reverse(boundaries);

and I found Waldmohr because it prevented the elements from being "fully worked out".
So, I agree that this seems to be a bug.
By the way, I use your bounds from europe_bounds_20111106.zip 

Ciao,
Gerd
