When I change templates in Netbeans, why doesn't anything happen?

I want to modify the "Java class" template, so that the class javadoc comment includes more than just the author. In Netbeans 6.8., I go to Tools > Templates > Java > Java Class, and modify the template. However, nothing seems to change. I tried restarting开发者_如何学编程 Netbeans, just in case, but the old template is still used.

How do I get Netbeans to recognize changes to the template for Java Classes?

Well, I was putting it off, but it seems to work. Changes to a template only affect New files. Be sure you aren't editing one template and instantiating another.
