I have been building with these options in gradle:

  sourceCompatibility = 1.8
  targetCompatibility = 1.8

And that doesn't solve the problem of the new "patch module" stuff added
in Java9.  That means you have to do some extra tricks to build parts of
Java itself.  The android.jar is the SDK jar, so it includes lots of
java.* classes.  This is the stuff that is stumping us.
