It is per VM even since JNI doesn't allow a given JNI native library to
be loaded by more than one class loader. (Because of "type safety in C
code no less! We wouldn't want JNI code to cache its defining
classloader and be surprized later that it is also linked against
another class with the same [method] name from a different class
loader...)
