Bundled .app Splash Splash Screen invocation?

[niagarasoft20-macosxportdev at yahoo.com]

Previously Java Mac developers were able to launch a Java 1.6 splash screen from within the app bundle using the info.plist key:

<key>SplashFile</key>
<string>$JAVAROOT/splash.gif</string>

... storing the splash.gif in the /XXX.app/Contents/Resources/Java/ directory.

How is this now being handled with the latest Java 1.7 OpenJDK mac-port implementation? 

What am I missing?
