Both the min and the max value are rounded down. This looks wrong.
Similar problem with the latitude values:
		int roundedMinLat = roundUp(minLat, shift);
		int roundedMaxLat = roundUp(maxLat, shift);

thanks, I changed it to the following - and now it works. I think someone should have a look at it, and check it in, as it makes much more sense....

		int roundedMinLon = roundDown(b.getMinLong(), shift);
		int roundedMaxLon = roundUp(b.getMaxLong(), shift);


		int roundedMinLat = roundDown(minLat, shift);
		int roundedMaxLat = roundUp(maxLat, shift);
