#1354 Missing java @override annotation for finalize

[J.T. Gilkeson]

For object wrapper classes, SWIG is generating:
protected void finalize() {
delete();
}

but this is missing the @Override annotation (which flags the SWIG-generated files as containing problems in many IDEs).

We're no longer using the SF trackers, and there's an open ticket covering this in the current issue tracker:

So I'm closing this in favour of that.
