Hibernate vs. Rails

Patrick Peak - the (unbiased?) author of the book Hibernate Quickly, has made a comparison of the persistence model behind Hibernate and Rails (=ActiveRecord):

http://www.theserverside.com/tt/articles/article.tss?l=RailsHibernate&asrc=EM_NLN_1944246&uid=2700586

The conclusion is, that Rails' ActiveRecord might be the best choice suited for small and simple data models, while Hibernate is best for complex data models with lots of joins and so forth.

While he might be right (I'm not in the exact right time and place to completely disagree on his conclusions), I wonder if he's aware of Mingle, and if he knows that Mingle is made in JRuby on Rails??
