openjdk 9 in ios - any sample xcode project or any sample using JavaLauncher interface?

[Bob Vandette]

You should see a README.txt file contained in the RunJava tar bundle.  
This explains how to build and populate the sample Xcode project with the Java
runtime.

The runjava-setup.s <http://runjava-setup.sg/>h script copies the Java runtime artifacts (including the image files) to
the Xcode project.
