Ok - I am now workin on Mesa3.1 compatibility.
This supports a better OpenGL 1.2 compatibility ...
Also the library bindings are better (using libGL.* instead of
lebMesaGL.* ).

Ok - please test your installation while runnung:
>java gl4java.GLContext

Where you will receive the true versions of the
native and java libs you are using !

I guess, you are using a different, not regular GL4Java native library,
because I do not know where the symbol
Java_gl4java_GLFuncJauJNI_glClearColor__FFFF
is needed for, I only know the symbol
Java_gl4java_GLFuncJauJNI_glClearColor !
I do not know how your java system wants the __FFFF extension !
Because you said that you do use Netscape,
please tell me the version - I do use:
	- glibc2.1
	- Netscape 4.7
	- mesa 3.0/3.1
	- GNU/Linux 2.2.13

Because your system wants the symbols for all the GL4Java native methods
with 
argument signature extensions for argument overloading,
I think this is about the JNI implementation of the java virtual
machine.

The native libraries of GL4Java for version 2.1.3.1 and above 
do not have signatures for arguments included, except for the 
special methods, which are overloaded, like: glColorPointer__III_3B !

Yours, Sven Goethel
