/**
* Tag interface for throws advice.
*
* There are not any methods on this interface, as methods are invoked by
* reflection. Implementing classes must implement methods of the form:
*
*
void afterThrowing([Method, args, target], ThrowableSubclass);
*
* Some examples of valid methods would be:
*
*
public void afterThrowing(Exception ex)
* public void afterThrowing(RemoteException)
* public void afterThrowing(Method method, Object[] args, Object target, Exception ex)
* public void afterThrowing(Method method, Object[] args, Object target, ServletException ex)
*
* The first three arguments are optional, and only useful if we want further
* information about the joinpoint, as in AspectJ after-throwing advice.
*
* Note: If a throws-advice method throws an exception itself, it will
* override the original exception (i.e. change the exception thrown to the user).
* The overriding exception will typically be a RuntimeException; this is compatible
* with any method signature. However, if a throws-advice method throws a checked
* exception, it will have to match the declared exceptions of the target method
* and is hence to some degree coupled to specific target method signatures.
* Do not throw an undeclared checked exception that is incompatible with
* the target method's signature!
