Sven is right:

System.out.println("GL2:   " + (GLProfile.isAvailable(GLProfile.GL2) ? "Yes" : "No"));
System.out.println("GL3:   " + (GLProfile.isAvailable(GLProfile.GL3) ? "Yes" : "No"));
System.out.println("GL3bc: " + (GLProfile.isAvailable(GLProfile.GL3bc) ? "Yes" : "No"));
System.out.println("GL4:   " + (GLProfile.isAvailable(GLProfile.GL4) ? "Yes" : "No"));
System.out.println("GL4bc: " + (GLProfile.isAvailable(GLProfile.GL4bc) ? "Yes" : "No"));

Edit.: You could have used "final GL gl = GLContext.getCurrentGL();" instead of passing GL instances. GLShader and GLUniform could probably be replaced by some JOGL classes (GLUniformData, ShaderCode, ShaderProgram, ShaderState, ShaderUtil). Using display lists isn't a good idea, the speed up isn't consistent across platforms and it is badly implemented in some drivers.
