Allowing every method in SAX interfaces to throw java.lang.Exception
basically disables Java compile-time exception checking.  I do not think
this is a good idea.

How about defining ApplicationException class which is basicaly an exception
container?

public void startDocument () throws ApplicationException {
    try {
        // some IO
    }
    catch (Exception ex) {
        throw new ApplicationException(ex);
    }
}
