Looking through the files I noticed two problems, all in the Java example. The first is that the labels a1 and a2 aren't formatted correctly. The numbers are red-boxed. Also I haven't figured quite out what the red boxes should show actually. The second problem is that overly long lines don't receive automatic linebreaks. So some text is practically invisible. Can that be helped?
