ATI Workaround of dispatching display()

Hi! I’m new to jogl. I was looking at the thread at the top about how to get started with jogl (the one with Test.java and TestRenderer.java). And I ran the code, which works fine, however it displays this message:

“Using ATI workaround of dispatching display() on event thread
Using ATI workaround of dispatching display() on event thread
Init GL is net.java.games.jogl.impl.windows.WindowsGLImpl”

Does anyone know what this means?
