App with bundled JRE doesn't work without Java installed

I'm following the official guide Java app packaging at http://docs.oracle.com/javase/7/docs/technotes/guides/jweb/packagingAppsForMac.html but the generated app bundle won't work if Java not installed on the system, even though JRE appeares to be bundled correctly (Contents/Plugins/jdk1.7.0_45.jdk).

As soon as I move the java install:

mv /System/Library/Frameworks/JavaVM.framework /tmp/

The app won't launch at all, the Icon doesn't even appear in the dock.

When I try to kick of JavaAppLauncher manually I get this error: 

./JavaAppLauncher
Error occurred during initialization of VM
java.lang.NullPointerException
    at java.util.Hashtable.put(Hashtable.java:514)
    at java.lang.System.initProperties(Native Method)
at java.lang.System.initializeSystemClass(System.java:1119)

Everything gets back to normal when I return Java to it's proper location. I'm wondering if the guide is maybe outdated, contains an error, or perhaps something I just missed.

Any help is appreaciated.

Add the new location of Java to the path. The default location is in the path already but since you moved it, you lose that automatic part.
