Lots of people are sleeping on modern Java, and it has had a lot of really nice changes, that, when put together, make it wholly different from what came before. One question: a lot of the Java enterprise ecosystem is based around entities (Hibernate and the like). Do you give guidance for how to work within that context? Can I use data oriented programming there?
