uiswing - layout - Error in SpringLayout page

I was following your SpringLayout tutorial and I got very strange results (namely strange heights for the components) when I tried to use the makeGrid method of the class SpringUtilities. Looking at the code of the method, you'll see that line 92 is

    getHeight();


while it should be

    getWidth();


A simple copy-paste mistake. It happens to all of us ;)
Other than that, a great tutorial.
