Class java.lang.Exception is the root of the exception class hierarchy. Thus, the throw statement must throw an object that is of type Exception or a subtype of Exception.

Here is what's right.
Wrong! The the root of the exception class hierarchy is class java.lang.Throwable. This class has two subclasses: java.lang.Error and java.lang.Exception.
A throw statement can throw any object o where o instanceof Throwable.
A catch clause can catch any object o where o instanceof Throwable.
The throws clause in a method signature can include any type that is Throwable or a subtype of Throwable.
