A test release is done !

The new revision may be incompatible with the previous, because:
	- The GLUFunc.gluNew* etc. methods uses the long type for 
	   the reference holder for quadric, tesselation, .. (old: int type) !

	   This is, because this new revision is completly 64bit clean !
	   All native reference holders are long !

	- You do not encapsulate your OpenGL calls within
		GLContext.gljMakeCurrent
			<your render code>
		GLContext.gljFree
	    e.g. within the GLCanvas.display method:
		glj.gljMakeCurrent();  // lock GL Context
			gl.glBegin();
			gl.glEnd();
			glj.gljSwap();
		glj.gljFree();	       // release GL Context

	All the demo's have been updated in the new test release,
	to work with 2.5.2.0 !

This new Version try's to use JDK >=1.3's JAWT API to handle with the native 
window ! The new library, which uses this is called "GL4JavaJauGljJNI13"  !

	I do have problems with IBM's JDK 1.3:
		No library "jawt" (linux: libjawt.so, win32: jawt.dll) exists at all !

	I do have problems with Sun's JDK 1.3 for Windows:
		No library "jawt" (linux: libjawt.so, win32: jawt.dll)
		is NOT found ! They do exist in jre/bin.

		Workaround: Add <java-home-dir>/jre/bin to your PATH environment variable !

Well, this version improves the multithreading behavior a lot.

I have attached the last CHANGES.txt changes ;-) here !

Thoughts & Ideas are wellcome !

Last but not least: 

	You can get the test release here:

Experience:
==========
	Linux 2.4.1, XFree86 4.0.2, kde 2.1 beta2:

		Command-Line JDK (1.1-1.3, sun, blackdown, ibm(no jawt)): 	OK !
			Indirect DRI (Mesa-Soft 3.3):		OK
			NVidia 0.96:				OK
				See NVidia notes below !

		Netscape + Netscape JVM:  					ERROR !
			does not work, because Netscape's JVM 
			implementation on linux looks like 
			not to handle long-types within the JNI API .. ?!

		Netscape + j2re-1_3_0_01: 					OK !
			Indirect DRI (Mesa-Soft 3.3):		OK
			NVidia 0.96:				OK
				See NVidia notes below !

		Konqueror (2.1 beta2):
			jdk 1.3-sun:						ERROR
				Applet runs, but nothing is visible !		

			jdk 1.3-ibm (no jawt):					OK !

			jdk 1.3-blackdown:					OK !
				Indirect DRI (Mesa-Soft 3.3):	OK
				NVidia 0.96:			OK
					See NVidia notes below !
			
	Win98/WinNT4.0(*):
		
		Command-Line JDK (1.1-1.3, sun): 				OK !
			Well, you have to start the java.exe from the 
			<jdk-path>/jre/bin/java.exe 
			Otherwise, the jawt.dll is not found !! BUG in JDK !! 

		IExplorer + MS-JVM buil 3802:					OK !
			JDirect usage ..

		JRE 1.3* Plugin + ( IExplorer | Netscape )				OK !

		Netscape + Netscape JVM 					OK !

	(*) WinNT 4.0:
		On my system (servicepack6, nvidia detonator3), 
		i cannot restart the applet !
		An read access to adress 0x000000 occures right from 
		NVidia's OGL implementation !!
		Looks like another bug within NVidia ?
		See NVidia notes below !
		Well, Win98 runs fine


NVidia Driver Note's:
================

The Linux 0.96 driver, and may be the winnt4.0 drivers,
looks like not being able to handle THREAD's very well !

Example:

JVM Process 1:
	JVM Process 1 - Thread 1:
		>MakeCurrent()
		>Free()
		This Produces many .X.err logs regarding to new created drawables for 
		same thread !(?)

If you use the same JVM process, and you start many applets -> native threads,
the GL context managment looks like very confused.
On Linux the GL rendering went slower and slower !
But a restarted JVM is fast as its first time !
Yes - GL4Java does destroy the glcontext 
and finalizes well !

comments, ideas are very wellcome !

kind regards, sven

Hi,

I've tried this release with my game Arkanae. The 3D works well and
quick, but there is a problem with events : i no longer receive keyboard
event (though it works well with GL4Java 2.5), and my Swing interface is
no longer refreshed... ???

It also prints this in the console :

GLContext.loadNativeLibraries ...
GLContext.loadNativeLibraries will do it !

???
