Neal, Sorry, I should have defined my terms.  I define a "true resource" as an object that can only used once, and then must be disposed of, never to be used again.

That's not the usual definition, (see <http://en.wikipedia.org/wiki/Resource_(computer_science)>), but OK. This definition would appear to include classes and interfaces such as

java.sql.Statement (close) java.nio.channels.FileLock (release) org.ietf.jgss.GSSCredential (dispose) java.awt.image.VolatileImage (flush)

I think one of these use cases is currently supported by the proposal.
