Hi Sean, thank you for clarifying this.
Just for the records: I downloaded the source tarball and the 1 million grouplens data set. Building the demo went smoothly. (I am using maven 2.2.1, btw.) (I actually downloaded the 10 million dataset, first. But after a couple of heap size increments and returning OutOfMemory exceptions I realized the mistake...)
