Ok I figured it out. It's an extensions thing. Maybe it's an OS X specific thing.
Java on OS X loads certain .jar files in /Library/Java/Extensions . And these seem to get loaded in regardless of
whetheryou tell eclipse specifically NOT to load them in. AND they seem to take precedence over anything in the class
path. So the .jar file I was compiling against matched the .jar file on my class path, but the .jar file that was
actuallybeing used was completely different.
I deleted everything in /Library/Java/Extensions and now it works.
