    java.lang.ClassNotFoundException: jddunit.function.classB

I ran it 100 times in IntelliJ with no failures. On the theory that maybe we ran out of disk I visually traced through the paths dealing w/ (jar) files and didn't see anywhere where the product might have been swallowing exceptions. So I don't know what went wrong.

Marked component as serialization because this is testing loading a Jar file that redefines a class which was the base class (of a derived class) loaded previously from a different jar file. Seems like the point of all that is mainly to support users updating their jar files without restarting their JVMs.
