/**
* Tag interface for throws advice.
*
* <p>There are not any methods on this interface, as methods are invoked by
* reflection. Implementing classes must implement methods of the form:
*
* <pre class="code">void afterThrowing([Method, args, target], ThrowableSubclass);</pre>
*
* <p>Some examples of valid methods would be:
*
* <pre class="code">public void afterThrowing(Exception ex)</pre>
* <pre class="code">public void afterThrowing(RemoteException)</pre>
* <pre class="code">public void afterThrowing(Method method, Object[] args, Object target, Exception ex)</pre>
* <pre class="code">public void afterThrowing(Method method, Object[] args, Object target, ServletException ex)</pre>
*
* The first three arguments are optional, and only useful if we want further
* information about the joinpoint, as in AspectJ <b>after-throwing</b> advice.
*
* <p><b>Note:</b> 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.
* <b>Do not throw an undeclared checked exception that is incompatible with
* the target method's signature!</b>
*
