I've now put :aot [ns1] in the projects.clj, did lein compile, then lein ring uberwar. There was no difference. The class loaders are distinct and instance? still returns false.
1. Did I do the AOT compile incorrectly? Is it even necessary? (The class files are in the war file but *all* of them are, not just ns1.) 2. If not, is it not being ``transmitted'' correctly into the war file? 3. Or, am I misunderstanding the problem? I'm really not clear how to fix this. A record constructed with the map->A constructor does not show up as being an instance of A. Why? Help!?
