I was cruising the opengl.org site and found a link to this resource: http://www.lighthouse3d.com/opengl/viewfrustum/index.php?camspace
From the article: "This method should be faster than the previous approaches where six planes are tested. In here, only a dot product is performed for each pair of planes, whereas in the previous approaches a dot product was performed for every plane, in the worst case scenario."
There is code for a generic C++ class that looks like it could be implemented in Java without much trouble. 
I've never seen view frustrum culling using this method before and thought it was interesting… enjoy. 8)
