> The spec says:
> If the servlet that is the target of a request dispatcher throws a runtime exception or
> a checked exception of type ServletException or IOException, it should be
> propagated to the calling servlet. All other exceptions should be wrapped as
> ServletExceptions and the root cause of the exception set to the original exception,
> as it should not be propagated.
> CatchExceptionFilter contains this code:
> if (!catchEvent.isHandled())
> {
>    if (e instanceof ServletException)
>    {
>       throw (ServletException) e;
>    }
>       else if (e instanceof IOException)
>    {
>       throw (IOException) e;
>    }
> }
> which takes care of ServletExceptions and IOExceptions, however, runtime exceptions are swallowed.
