I think that is in fact what Mark was suggesting and I think this is definitely a good idea. There are a lot of VMs that don't (want to) use JNI for their "native" methods. Having all native methods in the VM* classes makes this much easier.
On the other hand, too much abstraction increases the complexity of the classes, making maintenance more difficult. Even putting efficiency issues aside, I agree with Andrew - we would not want to do this in libgcj.
This assumption is not true for some VMs. My VM (IKVM) has no native
methods and I'm pretty sure this is also true for JAOS and maybe others.
I think its a mistake for classpath to try to be everything for everyone, even at the expense of elegance and efficiency. At some point, most implementations are going to have to modify it in some way in order to suit their special/custom needs.
