Getting OS X to Install Java 7 on App Launch

As you seem to be aware, with Java 7 and later you are expected to embed the JRE in your application bundle. I think the JavaFX packager will do this for you. The size is usually not relevant these days and the added reliability makes up for it anyway. You leave no room for the user to download the wrong version or to introduce a bug by downloading a later version that you haven't tested with.

I'm considering making my app require Java SE 7, but I want to ensure that users will be downloading the proper version (I'm aware I can bundle the JRE, but I would prefer not to add it since it would quadruple the app size). Ideally, I'd like for the dialog box shown above to continue to be shown, but instead of downloading Java SE 6, it downloads Java SE 7.
