I have a parent pom.xml for aggregating multiple separate project builds and a common/pom.xml file that contains the common dependencies per environment for the other builds.
When I execute the following command with the 2.1 version of the versions-maven-plugin then io-commons artifact in the sit1 profile contained within the common/pom.xml file has an updated version number.
Jason:~/test_case$ mvn org.codehaus.mojo:versions-maven-plugin:2.1:set -Psit1 -DgroupId="commons-io" -DartifactId="commons-io" -DoldVersion="1.0" -DnewVersion="1.2" -e -f pom.xml

However when I execute the code using the 2.2 version of the versions-maven-plugin I get a null pointer exception.

Here is a stripped down pair of pom files that have the described behaviour. The parent pom.xml:
