Yes this build error started appearing some time ago, and there is
discussion in the archives. From memory it didn't used to report an error,
even though it should be an error to write up beyond the document root.
After the "upgrade" to Cocoon-2.1 we started getting the more useful NPE.

The following search helps:

I wonder if that particular demo should be commented-out.
Not removed, see below.

You mean Example 6. The text explains the situation.

Yes, three different situations using the same "icon-a" source image.

Careful with changing the icon names, icon content, and example
numbers. The demo will then need to be changed and there are Jira
issues (e.g. FOR-635) and subsequent forrest-dev discussion, that
refer to examples by name "icon-a" etc. In fact one reason that i
created that demo was to try to resolve FOR-635.
