A plain Exception is completely useless, it can just as well be an 
assertion instead. Because it's not possible to extract any information 
from the exception (except for trying to parse the message which is a 
bad idea) resulting in not being able to act on a thrown exception. 
Which then results in it being pointless to catch the exception in the 
first place.

I think it's a bad design that it's possible created instances of 
Exception, it should either be an abstract class or an interface.
