Is there any documentation available on the G 1.1 classloader behaviour?

I am stuck trying to resolve what I suspect are classloader issues
while trying to separate applications into CAR files. If I could
understand the G 1.1 classloader implementation and the options that
affect its behaviour, I could hopefully figure a way out of my current
situation.

Can anyone point me to where the G 1.1 classloader is documented?
