Well, I will investigate a bit more. But my guess is here:
with jamvm and other vm you run interpreted code, where the classpath 
lib is the last bit in the chain. On gcj/libgcj you can build/run native 
apps where you link the libgcj against the app. As mentioned above, you 
can not link against a module on darwin.

But as said, I will provide some more details later. Also some tests. It 
may has also to do with the class loading mechanism.

Btw, I also successfully ran cp with jamvm :)
