In 2004 we (a small team of mostly very junior devs) were given a quite extensive and really excellent Java course.

Ahead of the course, we prepared by obsessing over our IntelliJ or Eclipse configs and had intense discussions about this.

To our surprise, the teacher urged us to use nothing but the basic JDK tools and Notepad. He wanted us to learn what's going on under the hood and also told us, that the productivity will probably be about the same.
