I have a Intel HD Graphics 4000 video card, and i don't do any optimizations to get a fast redraw (case when i use GL2).

I get the following exception when i'm trying to run a snippet with GL4 and vertex buffer objects
Exception in thread "main-AWTAnimator#00" com.jogamp.opengl.util.AnimatorBase$UncaughtAnimatorException: com.jogamp.opengl.GLException: Caught GLException: Method "glCreateBuffers" not available on thread main-AWTAnimator#00
        at com.jogamp.opengl.util.AWTAnimatorImpl.display(AWTAnimatorImpl.java:92)
        at com.jogamp.opengl.util.AnimatorBase.display(AnimatorBase.java:452)
        at com.jogamp.opengl.util.Animator$MainLoop.run(Animator.java:204)
        at java.lang.Thread.run(Thread.java:748)

The exception occurs in the method glCreateBuffers from GL4
FloatBuffer vertexBuffer = GLBuffers.newDirectFloatBuffer(vertexData);
ShortBuffer elementBuffer = GLBuffers.newDirectShortBuffer(elementData);
IntBuffer bufferName = GLBuffers.newDirectIntBuffer(Buffer.MAX);
gl.glCreateBuffers(Buffer.MAX, bufferName);

But everything it's working on a PC which has an Intel HD Graphics 620 video card

About JZY what version do you recommend me to use? I see on the JZY website is not specified anything about 1.0.2 but just about 1.0.0. Also i saw only 2 commits in the last year.
