Passing indirect NIO buffers to JOGL is a very bad idea as it will have to convert them to direct ones anyway.

I don't see any call to glVertexAttribPointer and glEnableVertexAttribArray :s

You have to call glBindbuffer, glVertexAttribPointer and glEnableVertexAttribArray in this order exactly like in the example. Maybe this would help you:

When you don't create a VAO, JOGL does it for you and your VBOs are bound to this implicitly created VAO.
