The test has to use @library because it is using processtools to launch 
another VM to run the "real" test via the jar file I am creating (and 
the fact it is a jar file is a critical part of the thing under test).

So I guess I'm going to have to run the jar tool passing the value of 
test.classes as the path to the actual classes I want in the jar, and 
list the actual classes individually.

Thanks,
David
