Furthermore, it's the top Google hit for 'objectify'.
Likewise I disagree with the idea that these two projects share the same space. A Java ORM and a Rails metaframework for avoiding ORM are not things which have a lot in common. I think the last time I observed a Rails hacker saying anything about AppEngine was 2007 or something.
As the lead developer of the Objectify project, and someone who makes a living through consulting related to Objectify, I am highly annoyed. I'm also talking to a trademark attorney to find out my options.
