> I'd like to send an email when wicket catches an unhandled exception. Also I want to customize the ExceptionErrorPage. Wicket offers getApplicationSettings().setInternalErrorPage(...) interface to set a custom internal error page. However, unlike the ExceptionErrorPage, InternalErrorPage does not receive the caught exception object or the current page object.
> In https://github.com/hannesd/wicket/commit/a33c6dff I extracted some code from DefaultExceptionMapper#internalMap into an extra method. Also I changed private to protected methods to make DefaultExceptionMapper reusable and extensible.
> I'd be nice if this patch or something similar enters wicket 6.x so that I don't have to duplicate 99% of DefaultExceptionMapper just to get my own version of ExceptionErrorPage.
