try with
   System.exit(0);

this is supposed to request the JVM to exit.

henri

Tried that but it didn't work.  I did isolate the piece of code that's causing the issue though.  Still have no idea how to fix it.

1. gl.glCompileShaderARB(vertexShader);

But the shaders are working just fine.  The glGetInfoLog reports that the shader compiled successfully.  But for some reason, when I exit the application, the JVM won't terminate.

I've tried this... but it doesn't help.

1.       gl.glUseProgramObjectARB(0);
2.       gl.glDetachShader(programObject, vertexShader);
3.       gl.glDeleteShader(vertexShader);
4.       gl.glDetachShader(programObject, fragmentShader);
5.       gl.glDeleteShader(fragmentShader);
6.       gl.glDeleteObjectARB(programObject);

I can't even get it to die with:

Runtime.getRuntime().halt(1);

Ok.. I got it to die.. but perhaps someone could give me some advice on minimizing the potential damage I may be doing, if any.  Here is what I had to do.

1. super.stop();  //after super.stop()
2.  try {
3.     if (OS.startsWith("Windows")) {
4.       String pidstr = java.lang.management.ManagementFactory.getRuntimeMXBean().getName();
5.       String pid[] = pidstr.split("@");
6.       Runtime.getRuntime().exec("taskkill /F /PID " + pid[0]).waitFor();
7.     }
8.   }
9.   catch (Exception e) {
10.   }

Ok.. ran jstack.  It runs fine when the program is running (output is below).  If I close the application (JVM still running because it won't close), jstack gives me "Access Denied".

Here is the output of the running application:

Hi jeff_g,

hi there,
have the same problem _ do not know how to solve it.
pressing PLAY starts JAVA.exe but pressing STOP does not end. CPU-running to 100%.
the only way to stop is killing file in task manager : but that's no solution for ever...
it just appears when running files using camera.
