콘테스트 개요

We are seeking a way to compile and run the below Java3D program using
jdk9 on a mac.

1. You MUST have a mac (not virtual mac, but a real mac!).
2. You MUST have had experience working with Java3D
3. You MUST answer the following questions to show you have read this contest:
q1: What do you see when you type: java -version on the terminal app?
q2: What version of Java3d do you use?
q3: Where are you getting your version of Java3D?

I think I may be able to narrow down the issue;
jogl-all-natives-macosx-universal.jar

contains a jnilib that will crash when loaded into the jvm under jdk9.
For example:
public static void main(String[] args) {

System.load("/Users/lyon/current/java/j4p/jars/j3d/foo/natives/macosx-universal/libnativewindow_awt.jnilib");
}
Emits:
#
# A fatal error has been detected by the Java Runtime Environment:
#
# SIGSEGV (0xb) at pc=0x0000000117a0a795, pid=65766, tid=6915

DO NOT bid higher than the maximum price.

import com.sun.j3d.utils.geometry.ColorCube;
import com.sun.j3d.utils.universe.SimpleUniverse;

import javax.media.j3d.BranchGroup;
import javax.media.j3d.Canvas3D;
import java.awt.*;

public class StillCube {

public StillCube() {

GraphicsConfiguration config =
SimpleUniverse.getPreferredConfiguration();

Canvas3D c3d = new Canvas3D(config);

// SimpleUniverse is a Convenience Utility class
SimpleUniverse su = new SimpleUniverse(c3d);

// This will move the ViewPlatform back a bit so the
// objects in the scene can be viewed.
su.getViewingPlatform().setNominalViewingTransform();

su.addBranchGraph(getBranchGroup());
Frame f = new Frame();
f.setLayout(new BorderLayout());
Panel p = new Panel(new BorderLayout());
p.add(BorderLayout.CENTER, c3d);
f.add(p, BorderLayout.CENTER);
f.setSize(200,200);
f.setVisible(true);
} // end of HelloJava3Da (constructor)

public BranchGroup getBranchGroup() {
// Create the root of the branch graph
BranchGroup bg = new BranchGroup();
bg.addChild(new ColorCube(.25));
bg.compile();

return bg;
} // end of CreateSceneGraph method of HelloJava3Da

// The following allows this to be run as an application
// as well as an applet

public static void main(String[] args) {
System.setProperty("sun.java2d.noddraw","true");
System.setProperty("sun.awt.noerasebackground", "true");
StillCube cube = new StillCube();

}

} // end of class HelloJava3Da

The winner will be hired to work on porting a java3d solution to webstart that will work with jdk9 as the sole jvm. This will be a long project.

There is an alternative set of libraries that might work on jdk9, but I was not able to get them working and represent another way to go (note the change in imports):
It is attached as "StillCube.java"

/Library/Java/Extensions/ the contents of that directory has:
gluegen-rt.jar jogl.jar libjogl_cg.jnilib
j3d-readme/ libgluegen-rt.jnilib vecmath.jar
j3dcore.jar libjogl.jnilib
j3dutils.jar libjogl_awt.jnilib

This is where I find: libjogl_awt.jnilib
Then I thought, perhaps the layout of /System/Library/Frameworks/JavaVM.framework
has changed with the new jdk..
cd /System/Library/Frameworks/JavaVM.framework/Versions/Current/
Commands/ JavaPluginCocoa.bundle/ Resources/
Frameworks/ JavaVM* _CodeSignature/
Headers/ Modules/
I know nothing about Modules (except that they are optional and that I watched
some youtubers try to explain it).
./Headers/jni.h
./Headers/jni_md.h
./Resources/.compatibility/libIASupport.jnilib
looks like there is a jni remnant here.

Hmm. Looks like a bunch of legacy jdirect stuff; com/apple/mrj/jdirect/
14compatibility.jar IASupport.jar libIASupport.jnilib*

  I made several more experiments... As I said, the best option would be to run a new executable JAR file that you should produce, which contains the manifest file denoting the main class and the main class requiring the appropriate JRE version. Repackaging the JAR file with the official tools seems to produce an error in relation to the signing. Starting over from the unpacked, compiled classes appears insensitive to the Manifest file fix; it appears runnable as a library... and still requires some J3D files in the path. Decompiled classes look like a nightmare. Abandon ship.
