The mechanism to load the jogl.dll or the libjogl.so files currently implemented in JOGL is suboptimal. Using System.loadLibrary works, but only the library is in found within a given path.

I've written a library loader, that is abled to
a) load jogl.dll / libjogl.so from a JAR/folder in the classpath
b) look for libjogl.so / jogl.dll in a place depending on the architechture (one is abled to put _all_ native libraries for _all_ architechtures supported into one JAR file or folder)

Well, for that loader to work, i have to disable JOGL own mechnism to load jogl.dll / libjogl.so.

Since all classes that need the native library call the load() method of the class NativeLibLoader, the following drop-in replacement will work and provide backward compatibility:

package net.java.games.jogl.impl;

public class NativeLibLoader
{
     private static volatile boolean DO_LOADING = true;
     private static boolean DONE_LOADING = false;

     public static void disableLoading()
     {
           DO_LOADING = false;
     }

     public static void enableLoading()
     {
           DO_LOADING = true;
     }

     public static synchronized void load()
     {
           if (DO_LOADING && !DONE_LOADING)
           {
                 System.loadLibrary("jogl");
                 DONE_LOADING = true;
           }
     }
}

of course the line System.loadLibrary("jogl"); has to be replaced by the more complex code that is currently in the static constructor of the class NativeLibLoader.
