@Hiroshi:
Can you clarify your observation ?
See 
http://docs.oracle.com/javase/6/docs/api/java/lang/reflect/Constructor.html#newInstance%28java.lang.Object...%29
                
> Class.newInstance() can throw any checked exceptions and must be encapsulated 
> with catching Exception

> There are some logics to call Class.newInstance() without catching Exception,
> for example, in the method CoprocessorHost.loadInstance().
> Class.newInstance() is declared to throw InstantiationException and 
> IllegalAccessException but indeed the method can throw any checked exceptions 
> without declaration.
