The DB exceptions are supposed to have two constructors: no-args and one String arg. The 1.4 Exception has two additional constructors that allow you to pass in a Throwable as well. Is anyone adding those to their DB exceptions?
I suppose you could argue that it's above what is asked for in the instructions but I'm thinking those additional constructors may come in useful later (when I actually get around to writing the DB client code )

Actually I think using the newer constructor will allow you to wrap the actual exception into a DBException and send it to the client with the entire stack trace a root cause with it. It is called Exception chaining and it was added to 1.4 so I also think that is another reason to use it.
