Hi, I've been trying to get a very simple JOGL program running on OSX 10.10, and I can't seem to pass the vertex information to the shaders correctly. After trying everything I could think of in my actual program, I've created a basic test case to help me figure out where I'm going wrong. This program draws a triangle, with the vertex information acting as the colors.

Here is the basic idea of the code:

My program generates this:

This indicates that the vertex data is all 0s. And I'm not seeing any errors when I repeatedly check glGetError.

See what I'm missing?
