Whereas the GNU Classpath port used the strategy of patching Classpath with core classes from Avian so as to minimize changes to the VM, this port uses the opposite strategy: abstract and isolate classpath-specific features in the VM similar to how we abstract away platform-specific features in system.h. This allows us to use an unmodified copy of OpenJDK's class library, including its core classes and augmented by a few VM-specific classes in the "avian" package.
