So this is like LWJGL in terms of game development?
Not quite. LWJGL is build from the ground up for games. This is more of a general purpose library. This one, like JOGL, has built the OpenGL binding through AWT and Swing. In addition to the Opengl binding, there is also a binding for the QuickTime API. You can even use video frames as textures, if you wanted. And there are several gui components and geometry classes. I'm thinking this would be quite useful for tools development.
And the reason I would choose it over JOGL is that it appears to not have the thread restriction JOGL has (the big JOGL turnoff for me).
