I used your code, but still ran into an error. This time it produced the error shown below. Just to help with the solving of this problem I am using a MacBook Pro early 2011 with an AMD Radeon HD 6750M graphics card.

Did you mean to remove the call to shader() from within the draw() method as when I reinsert the call to shader() in the draw method i either receive the same old runtime error with no real description of what has caused it (see below), or it crashes completely giving me the Exception in thread "AWT-EventQueue-0" javax.media.opengl.GLException: array offset argument "infoLog_offset" (0) equals or exceeds array length (0) (as shown above).
