Javadocs causing huge gitdiff

[Josh Elser]

Hi,

I've been playing around with yetus-0.1.0 RC1 on Accumulo (Maven-based 
Java project). I started doing something like the following:

`cd accumulo.git; test-patch test-patch --jenkins --basedir=. 
--project=Accumulo --plugins='all' ~/ACCUMULO-XXXX.patch`

This was going great, saw lots of plugins running. After my patch was 
applied, I noticed it that I stopped seeing output and CPU usage went 
way down. Best as I understand it: Yetus (with things inbetween these 
steps) built the Javadocs, applied the patch, and then calculated the 
diff of the patch. This ended up creating +500MB files (when I stopped 
it) because of the generated Javadocs being included in the diff 
calculation.

I'd like to figure out what went wrong (if it's a bug or user-error) and 
how to look into this further. Any suggestions?

Thanks!
