Standalone Mac launcher requests Java 1.6 runtime to be installed

The standalone launcher for Mac comes packaged with a Java runtime, and should run without/regardless any other runtime installed.

In actuality, this does not occur, and the user is prompted to install the Java 1.6 runtime upon executing the launcher.

Executing the Minecraft Updater within the app bundle of the Minecraft Launcher results in it downloading the runtime again, but doesn't solve the issue. Executing either executable (JavaApplicationStub and launcher) in the MacOS folder of the application bundle is successful in launching the Minecraft Launcher.
