####If I annotate a base class with @Entity, will a derived class be persisted?
-
No, you must annotate the derived class with @Entity (and possible @Table) as well. When polymorphism is introduced this might be changed.

####Does the object mapper perform any locking?
-
No, you must handle synchronization yourself using java synchronization techniques or distributed methods, like ZooKeeper.
