Currently deftype classes do no automatic namespace loading, unlike gen-class classes. The difference is gen-class classes are AOT-only, whereas deftype classes can be defined dynamically, where reloading namespaces would not be desired. I'm still thinking about how best to support Java consumption of deftype classes. For now, you will need some init glue code to load any support namespaces.
