The stack shows that ClassGenerator class is present, while
ClassGeneratorResourceLoader is not. Both are coming from the same
JAR. Very strange... Could you possibly try the same thing with
Cayenne 3.0M5?
Also you can debug it with "ant -v" to see what the "full.classpath"
is set to (maybe there's a conflicting Velocity installation or
something).
