If a public or protected method declares an exception that is not actually thrown, but an overriding method in a subclass DOES throw the exception, the exception declaration should not produce a warning in the superclass.

Example:

public class Foo {
  // Produces a warning, but shouldn't
  public void someMethod() throws SomeException {   
    // default implementation does nothing
  }

  // Produces a warning, but shouldn't
  public void anotherMethod() throws SomeException {   
    // default implementation does nothing
  }
}

public class Bar extends Foo {
  public someMethod() throws SomeException {
    boolean someResult = doSomething();
    if (!someResult) {
      throw SomeException();
    }
  }
}

public class Baz extends Bar {
  public void anotherMethod() throws SomeException {
    boolean anotherResult = doSomethingElse();
    if (!anotherResult ) {
      throw SomeException();
    }
  }
}
