title: Way to enumerate all elliptic curve names available in Java?
body: <p>Is there some way to enumerate all of the elliptic curve names that can be given to
  the <a href="https://docs.oracle.com/javase/8/docs/api/java/security/spec/ECGenParameterSpec.html" rel="noreferrer"><code>ECGenParameterSpec</code></a> constructor?  Or do you have to just throw a big list of curve names at the wall and see which ones do or don't throw execeptions when you try to use them?</p>
