You can only document a few exceptions. for example, JPA EntityManager.persist(object) can throw all kinds of exceptions, there is no way you can document all (db connection failure, constraint violation, object mismtach etc etc, I think EclipseLink have hundreds of exception codes, they didn't document them at the method or class level, but as a separate web page: https://wiki.eclipse.org/EclipseLink_Exception_Error_Reference_%28ELUG%29). There is another reason: you can plug in new database. JPA has no way to document the future new db exceptions.

InvocationTargetException is useful because it tells you it's not your component at fault, but the called code, whatever it does, to which you might react by trying again, or calling some other component, or returning a default result, whatever. -- Sebastian
