The Maven source code does not provide much information around the exception in this line of source. Can you provide the entire stacktrace using an online service like www.pastebin.com, and then send the URL to the paste to this list? (Do NOT send the stacktrace directly to this list.)
http://svn.apache.org/viewvc/maven/components/branches/maven-2.0.x/maven-core/src/main/java/org/apache/maven/DefaultMaven.java?annotate=688884 If you have a corrupt or not well-formed pom.xml file in a module (child, grandchild, etc) it might cause this exception. Are you sure all the pom.xml files are identical across all modules in this project, on both machines? Are they both running Windows and the same JDK etc? They must be some difference that explains the exception. (I've never seen this myself, that I can recall...)
