The point of avoiding ActiveRecord is because our data sources are disparate, meaning that they include databases, mainframes, and, in some cases, sources that expose only a message-based interfaces (JMS, etc). Furthermore, data from these sources needs to be mapped and processed through rules before being populated in model objects and presented to the client. Our Java data services layer handles all of this, so it's just a matter of integration Rails/Ruby with that interface. We intend to use Rails for our presentation tier only, not as a end-to-end solution. The Java framework already exists, and we want to reuse what we have available.
