I was following the instructions for the ColorSwitch tutorial:

    To create the container:
    Choose File   New.

    The Template Chooser is displayed.

    In the Template Chooser, expand Swing Forms, and then select JFrame.

    A description of the JFrame component appears in the pane on the right.

    Type ColorSwitch in the Name field and click the Browse button next to the
Package field.

    In the New dialog box that appears, type colorswitch in the Package field
and click OK.

When I typed the initial "c", I got a NullPointerException.
