The problem seems to come from some sort of conflict between the dependencies
of httpclient, which is now included in the Maven core as part of the
non-lightweight http wagon, and other users of log4j (plugins, mainly). Still
tracking down the exact cause of the problem, trying to determine how best to
fix it. I'm including Benjamin Bentmann's original test case for this issue,
since he's the one who has done most of the legwork at this point.

1. unpack and install the IT plugin using Maven
2. Using the attached pom.xml as the project POM, try `mvn initialize -X`
