maven project job errors while parsing a largish pom that contains <?m2e ignore?> 

re-creatable in a similar way to the dependency bug (fixed in v3.1.0) described here :  https://github.com/codehaus-plexus/plexus-utils/issues/22 

To recreate the problem, set up a maven project job with the attached plexus-pom.xml, and run 'mvn clean verify'
