Description
Checked out doxia-site from https://github.com/apache/maven-doxia-site and ran mvn verify on Linux with JDK 8.
I estimate there's three different errors here to make this happen. This issue is for whatever in core is causing an InternalErrorException when likely faced with a somehow broken project setup.
