I agree with Tom here. I think it is best if GNU Classpath sticks with
providing only a JNI/POSIX/C based native reference implementation. We
just need to define the VMNative/Interface parts well enough for 1.0 to
make a CNI/C#/Java/WhatEver implementation easy. Then if people want a
CNI implementation of those VMInterface classes they can just look at
the libgcj implementation.

I think that ResourceBundle is a good candidate for introducing a
VMResourceBundle class that defines the (callback) methods that a VM
might want to implement for optimization (Classpath would supply a
default java based implementation).
