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

[Bob Vandette]

The jimage files are the new JDK 9 Modular Runtime Image files for the Java runtime classes.
They replace the existing rt.jar and other runtime jar files.

https://bugs.openjdk.java.net/browse/JDK-8061971 <https://bugs.openjdk.java.net/browse/JDK-8061971>

The complete list of changes coming in JDK 9 can be found here:
