title: Jar sizes different for different people
body: <p>So, I have an interesting question. I have three people using the same ant build xml file creating a jar file for an Eclipse project that hasn't changed in two months. We each do a build using this xml file and we each get a different sized jar (62 KB, 78 KB, and 101 KB).  Also, when I do a winmerge on them, they are dramatically different.</p>
  
  <p>What could cause this difference?</p>
