The thing that most people use GLUT for (afaik), is window initialization and management. The reason for this is that creating a window and rendering to it is rather different on Win32, MacOSX, Linux - and GLUT simpleifies this greatly because of a single interface.
But since LWJGL is a Java wrapper, we're actually doing sortof the same as GLUT, in that you just call Display.create to create a window - and we sort all of the issues per platform.
That said, there are some methods for rendering a cube or other stuff which a few use from GLUT. But its not something that anybody have looked at. If one wanted to do GLUT in Java I think it would be a fairly easy task. But from my point of view, it isn't needed.
