Make tests pass if you built w/ Maven and not w/ Eclipse

One of the tests stupidly had hard-coded "build/" which only exists
if you use Ant or Eclipse, not Maven. Instead, we put a renamed copy
of the class file under src/main/resources, and load it via
class.getResourceAsStream, which seems to work.
