Hi Robert, The Apache Commons Primitives Collection project seems to be pretty inactive. The last release was in 2003, there are many dead links on the website. I would not suggest to use it. HPPC and fastutil seem pretty similar to me. Both have a somewhat active mailing list and up-to-date releases. Apache Giraph is using fastutil. In my opinion, its up to you to decide what you want to use.
